Unsupported So-Cal Interstate Highway (126 miles of road & path) 0.8

This is what Los Injurus was built from, though be aware the Los Injurus version is very heavily re-worked, and has 10~15% more land than this one, and much more roads.
If you have both this map and Los Injurus installed YOU WILL HAVE PROBLEMS. You must make sure to eradicate your so_cal zip file before running Los Injurus with any desire to be successful. The reason this map was chosen in-stead of building a new city, is this had all the highways etc that are needed for a city to be built, it was merely just missing the city. This way I can build areas at my leisure compared to having to build all the connecting highways / roads, too, only to rip half of them up later (well I am entirely re-doing the highways but as state above, I don't have to worry about it so much on a time-level). Think of it as a good template if my explanation failed in some manner (wouldn't be shocking).
So yes, this was what it was before it was a city. There a lot more to it than just what meets the eye though.
Please don't get upset if you have mis-match issues with having run this one, there is no warranty on being able to do so. Clear cache if you have issues. Otherwise while this is available it is UNSUPPORTED.

You're looking for LOS INJURUS City map, search for it on here. Los Injurus was what I originally intended So-Cal to be, I just didn't have enough knowledge or skill yet at the time I made this.
Sorry for the confusion that may have been caused.

One of these days I have to fix this up a bit so it runs a little better. It's an oldie but it's a goodie! If you just want LOTS of ROAD AND TERRAIN and not much else THIS IS YOUR MAP.

The absolutely immense draw-count overwhelms current tech. I have an update that will make it flawless FPS. It's because of the draw distance, there's just so many bridges, railings, road surfaces and landscape to draw, for so many miles. If you go into THELEVELINFO in the f1 object editor, inside the F11 map editor (you can search for LEVELINFO), and turn down the far view plane (distance) to something like 2000~3000 meters, it'll not draw things beyond that many meters (then add just a smidge of fog, like 0.0005 or something small, experiment, higher # equals more fog). Basically, it's drawing 'too much stuff' for current video boards/Dx11. I will have an update that fixes this and adds in the missing AI on a bridge when I am done with my Tail of the Dragon map. It used to lag looking @ the ocean, that was a game issue, however, lag looking at the map is horrendous as you said. Pardon my fail, but it still runs.
Update will fix the FPS issue and the fact that all the bridge pillars disappeared but can still be hit (they're not in the road).
Look for update next month sometime, after Tail of the Dragon comes out.

It's a pretty good system you've got so it should remain playable. An FPS improving update is coming within the next 10 days hopefully. It will solely add more FPS but not really much else to the map, so that more folks can enjoy the map. Thanks for the kind words and writing in, I've tried hard to produce an enjoyable race track that is dressed up as a highway rather convincingly :) So if you just want to cruise, my maps are made for it, and they all work with the AI rather decently, so have a few chases if you like.

An FPS update is coming hopefully within the next 10 days. This should solve your issues with the frame-rate issues when looking @ the entire map from one side. Admittedly, I could have, and should have fixed this oversight much sooner, that's 100% my fault & doing. I will make good on this issue by pushing the update out this or next week sometime (after it gets significant testing of-course). FPS in next update should be at-least 1.5~2.5X better than what you're getting depending on how bad it was.
Thanks for writing in with system info in there so I can better make maps for who plays them.
Nevada Interstate just got it's FPS update, so check it out if the 7.x version was too slow or had texture errors of any kind.

Beamng.drive engine optimizations my friend, plus I converted the last non-dds textures to native direct-draw format (works with compression and hence faster rendering). If your video is slow knock off reflections if they're on, if your cpu is holding you up turn off shadows (or leave them on for just the car). This is a pretty complex map to render with a high draw-distance (lots of poly's) so I am quite glad it runs on the APU for you. Also, the near-the-edge slowdown of v 0.7 and 0.8 game engine seems to be addressed now, especially good for the highway that rings the outside of the map for the most part.

Yes, this does have rather abrupt pavement changes, but that is because not all highways are 100% paved at the same time, it simulates aging of pavement better this way, as to not be so bland and boring.
This map was made for fun primarily, so not all roads are 100% realistic, some are just plain crazy jumps too.
This map might be updated in the future with more buildings as models become available in the mod community here at Beamng, so as to not be so boring. Thanks for writing in.

Your cpu is just fine for the task at hand. Only more simultaneous cars would benefit from having a more multi-core cpu like an i5 or i7, aside of the GHZ speed increase that comes with the upgrade. I am currently thinking it's more game-engine related at the moment, but I am still tinkering about with it trying a few things. This map does use over half of the alotted objects total allowed per-map so it's up-there in 'work load' for the game engine. Thanks for writing in and glad you enjoyed it.

Nice review. I saw your CPU is overheating. Try and see if you can UNDERCLOCK the PC's processor by a few hundred megahertz (like put it to 3.2ghz instead of 3.5ghz, or disable turbo mode in the bios). Also, try taking the side off (if you don't void the warranty in the process, IF it's under warranty yet), and aiming a desk fan at the PC.
The INTEL stock cooler that many OEM's include with the chips themselves in the PC isn't nearly good enough to do it's job when running this game. My i7 4790k barely keeps cool at it's turbo speed with a 100$ air cooler, where the stock cooler couldn't even hold it's stock speed, and almost never the turbo speed. A hyper 212 by cooler master is a good cheap cooler, that should fit in most PC's but I'd recommend taking yours to a PC shop, and getting the cooler upgraded. Get the bolt-down kind, not the push-pin kind. Maybe a knowledgeable friend can help you here.
Please make sure your PC is also dust free. A good can of compressed air can help this but best to do this outside or in the garage.
Disabling car collisions also can help reduce cpu usage to keep it from overheating. If you're on a laptop a cooling pad can help a LOT.
--Good luck and glad you enjoyed the map.

Glad it's running well on your system. There's been a performance issue with the water on the map (which I reduced slightly in detail, though the water 'looks' better / more realistic this time around, I did make the reflection less taxing to the GPU), a performance issue I've only been able to attribute to the game engine itself. Welcome to pre-release software + ever-in-beta maps :) Thanks for posting system specs, performance info/feedback, and taking the time to write in. This is a map for 'just cruising' or when boredom inevitably DOES occur, there's *PLENTY* of jumps to go around for hours on. Most all can be conquered with a livable car, and some cars can do the same one multiple times :) The results can be downright hilarious at times...
If you have any trouble landing it, remember that while airborne, revving the engine can help keep the nose up, brakes make the nose dive more, but some cars cannot be helped at all by this, so do give it a try.
--cheers!
