Lower FPS than expected

Similar to beech (he posted not too long ago), I'm also not too happy with my computer's performance. Example: Bruckell Moonhawk on Grid Pure, 25 FPS. And that's with all the graphics down to the minimum and no Post-FX. There isn't a real drop in performance when there's vegetation (i.e. maps don't really matter); the biggest factor seems to be cars.

This is what I've got:
-AMD FX-8329 (3.5 GHz with 8 cores, liquid cooled)
-AMD Radeo HD 7990
-8GB DDR3 RAM
-2TB HDD
-ASUS motherboard

I don't know if it's hardware or software related. Maybe it has to do with one of the specific components or how it works with the others. It could also be software related, but I've got the newest drivers for everything, as with BIOS. Any suggestions?

 

something seems to be wrong on your end, as i get 50+ fps on pure gridmap with the moonhawk, and your cpu is quite a bit more powerful than mine

 

I'm not sure either. I just rechecked, and with two moonhawks I don't even get more than 14. It's not just that either; it's latency. With two of them I get .6-.7 of a seconds of delay. Other cars are better, with the Bolide FT-40R I get about .2-.3 sec of latency. Is that a hint towards anything?

EDIT: None of the 8 cores goes over 50% usage, regardless if there are 1 or more vehicles.

 

When you're in game, on a map with a vehicle spawned, your fps is what?
Then, press the "J" key to stop physics. What's your fps then?

 

vs.

 

That isn't the most reliable FPS test, use CTRL+F instead. (T3D vs. BNG debug)

However, it looks like you have a CPU issue as you only have 1840 physics FPS (bottom right), you should have 2000.

 

don't use that fps meter, it's for something else (i believe lua performance, not sure though) just use CTRL+F, or open fraps if you have it (contrary to belief, fraps only affects performance when you're recording, it won't affect your performance if you only open it)

 

Same thing here. My 870 should smash the game, but I tend to hover in the 30-40fps area. Race update should bring a lot more fps for me and probably you.

 

Not really, your intel for gaming >>>> any amd.

Anyway, it seems you have a problem with your CPU that can't even handle 1 car, as pulley999 already pointed out, your Physics FPS should be 2000 with 1 or multiple cars, but you only get 1800 with 1.

You should put all the graphics settings to maximum with that computer.


P.S: Post CPU temperatures while playing, obviously there is something wrong with the CPU.

 

*sigh*
For older/poorly coded games that don't properly use threads, yes intel is better. However, in beamng drive, all 4 module/8 core/8 thread whatever's are being used. The FX-8000 series has pretty ok IPC and handles bng fine. The issue is his CPU not being utilized, not the CPU itself.

 

For what I've seen in other threads those fx-8000 don't do that well BeamNG compared to intel. Let's not turn this into a amd vs intel

 

then you shouldn't have made the comparison in the first place anyway, my 8350/280x never go below 40fps on highest setting on the island maps. have you done the crossfire fix? i saw a thread a while back.

 

Okay, so I tried the CTR+F option (thanks for the tip btw, much more reliable), and I've found out something interesting: with 1 moonhawk I get 24 FPS, yet with 2 I get 22.5 or 23. Add a 3rd car and it dips to around 21 FPS. The loads on the CPU are kinda weird, with only every other core being used to around 40% at one time (with 1 car), if at all. With 3 cars I start to see the first 4 cores being used to up to 80%, and overall I get temps ranging between 33 *C and 38 *C. I think it is a problem one my end which is kinda sad since I bet there's a whole lot more power to be used. One more thing: the input lag does not increase with more cars. It's generally terrible.

 

If your CPU is faster than your GPU, then it's waiting for your GPU to catch up,
that's why your CPU wouldn't flexing as much muscle as it could.

That's what it sounds like to me anyway.

 

I appreciate the help, but it's definitely something on my end. If I figure out something that might be of use to others with AMD specific problems, I'll post again.

 

the fx-8000 series is literally 30% slower at single threaded stuff than comparable intel processors.

you're also wrong about beamng core usage: each car is simulated in one thread only.

Okay, the Intel/AMD war needs to stop. They're both good so shut up.

What is your GPU usage in Drive? (You can check this with GPUz or the MSI Afterburner graphs.)

I actually do get around the same performance with a single stock Moonhawk on Grid map. (20-25FPS) But that's just because of my crap A8-3850. (2GB 650ti GPU) Is it just with the Moonhawk or do you get crap FPS with other vehicles?

 

I highly doubt its the gpu, a 7990 is 2 7970/280x(which i have) GPUs , maybe you should overclock, i've reached 4.5 ghz with a hyper 212 evo, you would do fine with any watercooler

 

Don't call me out on my facts, I know what I'm talking about thank-you-very-much.
Yes, the 8000 series has a lower IPC (I said that didn't I? Yes, yes I did) But it is more than enough for any multi threaded task. BNG is multi-threaded, it's good for BNG. (Ask Noah if you don't believe me, he is running a solid 60fps on a 8000 chip. It's either a 8150 or 8320 IIRC.) Also, I'm 98% sure BNG is multithreaded with single cars. One car can be split across 2+ threads. (Devs correct me if I'm wrong.)

No matter if OPs CPU is a i7 4930k, if he isn't getting acceptable frames and his CPU usage isn't right then it isn't the CPUs performance.
This isn't even about Intel vs AMD, (I'm more of an intel guy) you're just bringing up irrelevant points.

This is the problem.
