Roane County, Tennessee, USA 19.3.1

There's an update pending, it should help with some of the texture issues and be better compatible with traffic / traffic tool - there's also some new highway textures too. It'll be posted whenever the moderators have a chance.
The shaking is the non-precise nature of floating point (e.g. rounded math) values at a far distance. Simply put, either one can ignore the shake when the vehicle is stopped (it does not affect crashing), or one can play smaller maps where that does not occur. That is the only downside to such a large map.

You can run it, but I'd wait about two weeks for the better version that should be up after mid-month. I am currently working on fixing the numerous texture bugs (caused by feature changes in game-updates), updating the bridges, and the road textures. You'll have a better experience, if you wait. However, that being said, if you can forgo driving around Kingston (it has a very glitchy road in it that flickers like mad), it's otherwise not TOO bad aside of the parking-lots with 'no_texture' embossed on them.
The new version should also have great 'out of the box' functionality with the traffic tool that's recently come out.
So keep posted, and look back in about 10~12 days time.
Your specs SHOULD run this map, but 8gb of RAM won't allow much AI without serious lagging as the system runs out of RAM. If you play solo you should be fine - just close the web browser 1st.

The Roane Racer was more of an inside joke with the internal beta-test crowd before it was released, but the internal beta was fine, so I left it in! Unfortunately due to game updates, there is some glitching in Kingston on the main route as the texture underneath the road glitches through, and a bit of a transparency issues on some railings/fences at times (not too bad).

Send me some pictures in-game near the spawn points. If it looks and runs good like the pictures, you'll know it's the right thing. It just has a bit of a throw-back icon.

I am downloading it (over my slow 90's-era DSL) again to verify that yes it's the correct version.

Made most signs and names myself. There's a couple off the internet (most aren't implemented, the ones I made are however), and a few fan-made ones like Lame Stop, and a number of others that will eventually be added.

I figured as much that if I went through all the trouble to make a sign, it might as well be fun or funny and interesting. Not just some boring name that adds nothing to the map.

The new update took performance on a comparable RX 480 8gb card from 20~25fps in worst-case spots in Downtown Harriman (the default spawn is here), up to 65~75fps minimum. That's with reflections on close to minimum and all other details cranked.
Even for folks (who may choose to read this) with video cards that are only HALF as powerful, they should still be able to enjoy 30fps or better everywhere with reflections, and as-always, turning off reflections vastly improves the frame-rates for machines with marginal video processing power. A strong processor, integrated graphics, and low settings will also net good performance on very modest settings. Your mileage may vary though as not all integrated performance is created equal. So long as you bring a machine with enough memory (8gb is bare-minimum and does not include RAM deducted for integrated video), you should be fine! 16GB means even on integrated video, you would still be able to have a few AI players to chase around. It will eat through 8GB very quickly though, so be mindful, and 4GB VRAM is to be considered a starting point for MAX graphics texture detail settings, as it will use 3800mb just loading the map with one vehicle in play as-of last check 1 year ago.
So do enjoy, and keep an eye peeled for an update, featuring redone custom bridges, possibly some new buildings, and a possible (but not promised) improvement in FPS (if it's not taken up by new content). I should hopefully get this out by spring, provided my c: drive doesn't eat itself again (I backup, but it still takes time to fix).
--Cheers!

Will be updated for 0.15 when I get my next private beta of Los Injurus City map out at the end of the month. Was planning on doing it sooner but had other issues here that pushed it back considerably.
Aside of a few issues with texture-normals (bump-mapping, per-say), overlaying the 'no-texture' onto some textures, some flickering issues, and a few transparency issues on some railings/fences, it does otherwise run fine. So if you don't mind the texture boo-boos in some spots, you'll be fine for now.
--Thanks for the review!

No, not specifically, but it still runs just fine (I have tested it).
Where I used to get 25~40fps in downtown Harriman (the default spawn is there), with reflections on basic, all other things like Shadows and SSAO on, and texture detail max (4gb VRAM needed), I now get 65~90+fps in the downtown area on 0.15.
Errata for 0.15:
Railing and fence translucent/transparent textures show up as white or texture-on-white backround and solid.
Lots of flickering going on in-front of WORST BUY in Kingston.
I did not check if the UI MAP APP is still slow/lagging out the UI, that may have been fixed in 0.14 or 0.15.

An update is planned to replace all bridges with custom models I've made, and do a few odds-and-ends like fix the bugs.

With the new game update for 0.15 game version, your performance worries are pretty much over. Even a 750Ti 1gb will run it fine on medium/low with reflections off (don't use HIGH texture detail without 4gb of VRAM).

The update murdered some of the graphics. More like some errors that were overlooked by the game engine, and transparent to the user (and sometimes the modder) and some that still worked anyways, no longer work. I will have an update to this, hopefully within a few weeks.
So it's not you, it's the map, on game version 0.14 and above.

6 months later, it did FINALLY get that update.
So come back and try this map again, I promise you'll love it better than the leading brand or...
Well, just try it and see for yourself, now new and improved, with less than half the fat, calories, half the nutrients, and almost none of the stinking graphics glitches that plagued the old version.
Add Traffic Tool to your order and get extra good times absolutely FREE!

Wow, thanks!
This is by far one of the most detailed reviews given on this map (and there are dozens and dozens). I am so glad you enjoyed it evidently as much as I did making it. It'll even get a face lift one day, too, in the somewhat distant future.
Currently working on my all-custom city map, so thanks for the inspiration and encouragement, it's highly appreciated (and often very needed).
It's the go-to map when you want to just 'drive and drive' and not be so confined. Sometimes I wish to do just that - and often many others do, too.
2500+ hours went into this map, possibly up to 2800~3000 hours.
Hopefully my city map (though one-quarter the square mileage in size) will top this one by leaps and bounds. I am aiming for that number 1 spot on mod rankings - and with a mod everyone will be able to run!
I really appreciate the review buddy. Thanks again!

Sorry for the late reply, been busy on another map project lately.
It will run fine without reflections, you should be just fine. It may take up to 4~5 minutes to load initially on a 5400rpm HDD (<1min~1.5min on SSD), so busy yourself on some websites for a few minutes, or read one or two of my very long replies. You have plenty of RAM but if you add in some AI be careful as this AI in the game hogs RAM *FAST* on a large map, so try 3~4 cars max for a little bit, keeping an eye on RAM use. If you go over it will start to lag hard or crash to desktop with a 0xFFFFFFFF error. The CPU should be fine. Downtown Harriman hits draw-call limits very hard though, just be wary. Shutting Shadows (and reflections) off limits how hard DRAW CALLS hits the game performance. In the future I will ratify this a little bit, but not anytime in the very immediate future.

It takes a little longer to load the 1st time due to model caching, which with a modest CPU but a slow drive could take a while. Leave the game go for 5 minutes or possibly a little longer and go make tea, and cake.

Hopefully I don't offend you with my knowledge-filled posts. When you start getting middle-aged or older, you may have a lot of knowledge you wish to share with others in long posts like mine!
--Cheers and hope you enjoyed the map, it was a lot of work.

Glad you like it & am glad to hear that buddy. Sometimes it's just fun to cruise around... with no where to be but just cruise. Sometimes it's more fun to haul pianos around town in a truck with 16~20 of them jammed in (or a bus full of them). Sometimes I just haul them off the nearest cliff. That'll learn those pesky pianos.
This map is not abandoned nor finished, it will be updated again one day but is currently on the back burner while I work on my city map. In due time I'll be porting some models over to this map from the city map, where it matters (bridges, fast food places, road puzzle pieces, a sign or two, etc).
Do keep an eye out for the up-and-coming city map in the coming weeks/months/whenever!
--Enjoy!

With over 2500 hours logged, and possibly several hundred more hours not logged, it's had a lot of time sunk into it. I stuck it on the back burner for now as I picked up 3d Modeling - however - all is not lost. Far from it actually. I am working on a large city map right now, which while it does not have the square miles of space like this map has, it's 10.6km x 10.6km, and it's going to be a city that will dwarf all cities in this game (as if there were more than just a handful). It's also going to run well, so do not worry - I have a tester with an i7 9xx CPU, 12GB RAM, Radeon 6750 1GB DDR3 computer configuration that can get 55~60fps on Lowest settings on it's fully detailed parts. So it won't be nearly as big of a deal to run as this map's 'Down-town Harriman' portion - which really runs rather slow, if you don't turn off reflections.
The new map can be previewed here:
https://www.beamng.com/threads/a-new-city-map-unnamed.57055/
It's going to be an awesome GTA-SA inspired city that 'almost anyone can run decently' provided you meet the requirements for the base-game and have 8gb of RAM (it currently requires under 4gb free). It's also the spiritual successor to Generic City, with a complete modular road kit that will come out along-side the map. This will enable ANYONE to build a city, provided they can work the map editor and have a heap of buildings - and of course a LOT of time.

So thanks for the great review!

Thanks, I spent over 2500 hours on this. Whenever I get the chance to update the bridges and introduce some new buildings (and mobile homes!) I am sure you'll be pleased with that. Until then please keep tabs on the new unnamed city map here - it's not out yet though:

--Cheers & thanks for the review!

Thanks for the awesome review.
The draw distance would surely be a let-down for airplane users.
Open up your level editor with F11 when NOT in full screen.
Press F1 to make sure you're in the 'OBJECT EDITOR' mode (1st button on the menu panel above, too).
Mosey over to the right-side pane. Type LEVEL into the search box above the list box displaying map contents. It should come up with THELEVELINFO - now click that blue icon that popped up.
If you click this, Raise the VISIBLEDISTANCE box up from it's 800 meter (or similar) setting to something like 2000~4000 meters (that's two to four KM), this is how far the map will draw from the player.
But wait, one more thing, you still can't entirely SEE this far due to fog.
Change the FOGDENSITY setting by adding another 0 just after the decimal spot (to the right of the decimal), to make the fog 10 times LESS dense. You can also just set fog density to 0 and achieve almost the same.
Now you're done with that and can see! But it's CLOUDY/OVERCAST!
Lets brighten things back up! (this part is totally optional, you can hit save and just be done with it and hit f11 to exit the editor and play if you want)
Type SUNSKY into the search box just like you did LEVEL before.
Click SUNSKY when it comes up in the box below.
Find the BRIGHTNESS setting (scroll down a tad) and set it to 1, it will have been like 0.6~0.8 something if I remember correctly. This will brighten up the map nicely so it's like a clear day.
You may now hit SAVE from the FILE MENU BAR, and press F11 to exit the editor.
CAUTION: If you clear cache you will have to do this again, but this review response will remain here, it's pretty easy to do. You can also fish your stuff out of beamng.drive/backups folder if needed. This level's directory/project name is 'southernhighway', for future reference. If you see this folder in your /beamng.drive/levels/ folder, those are the changes you made.

Thanks for the good review again - this response is not only a way to say 'you're welcome' back but also to help others who may feel the same. This works on any map, by the way. Happy flying.
--Cheers!

Thanks for the review!
The mini-map glitch with the HUD is due to having the mini-map app open, at-least that's what did in in 0.9.x ~ 0.12.x game versions. If this is still the same bug, just shut the mini-map off while using this map and the rest of the apps on the HUD should be fine. There's just too many roads for it to process, and it gets backlogged (but in the countryside it's fine, because there are much less roads to 'see' on it).
That being said, the in-dash or on-dash GPS should be as fine to use as it's always been.
Glad you liked the map, as it's thousands of hours of work! I am working on a city map now that might take that long also, so keep an eye for it in the coming months.
--Cheers!

Do you meet the system requirements?
All these other reviewers ran the map just fine. The discussion thread has hundreds of replies. Maybe you should have posted this there.
I will let this review stay here so people can see what you're about, when given other people's works with thousands of hours put into them (yes, thousands of hours) for free, and how thankful you are.
--Thanks!

For some reason there's an issue with skidding on some maps, when tire skid decals would be generated. It's not necessarily the map that means it will happen. Sometimes it does it on another one of my maps for me when a second car is falling towards the center of The Earth, but not always, and never this one (on this game version). It's something odd in the game engine, I haven't been able to source, or pin it down to a certain condition. I can't really explain it much other than that, nor can I do much about it.

This map will make short work of cellular data plans, let that be known. Thank-you for trying out the map and look up the forum thread 'development screenshots' to see what is in-store for the future. This map is not dead, just on the back-burner for this very moment while I have LOTS of modeling work to do.

--Cheers and welcome to TN USA!

If it's not too much of a bummer, turn off Reflections or at-least lower them somewhat from the maximum. This is a large map made from a real county here in Tennessee. It's not a city made into a game from fiction. So it doesn't always perform as consistently as if it was made 'for the game'.
I just recently increased base-line performance by 25~50% in the most recent update.

Thank-you for the kind words though. Maybe in the future I will be able to squeeze out a little more performance (maybe 1~5fps on average, tops), but as-of-current, it's not looking like I can do much better than what I currently have done already.
Do buy more RAM when possible, it will help avoid lag from things swapping in and out of system memory or the installation drive (hard drive or ssd), when you start getting close to 80% of total RAM usage. I know it is expensive (wait if you must, I sure am), as during content-creation days here I get the 'low ram warning' on BeamNG.Drive even with 16gb of system memory.

--Cheers!
