Graphics Card Performance Drop

I'm guessing that it should be fine from now on.

 

One possibility is those driver updates and also updates to Windows too. With support ticket devs could see lot more, but they have to ask it themselves I guess, but you could go here https://supportid.beamng.com/ and do by instructions, then post ID and report that post, maybe they would get back to you then.[/QUOTE]

So I did some more digging on this issue earlier today and came across a few forum posts where people were recommending the setting of min and max frequency settings in the Radeon software in order to deal with FPS fluctuations and generally poor performance of these cards. I set the min frequency to 2,015 Mhz and max frequency to 2,115 Mhz with the other settings remaining the same. The FPS increased to a relatively stable 105-120 FPS (similar to the fluctuations I would see with my previous card) with power usage of around 150W and continuous fluctuations in total card usage in terms of %. It appears that these settings might have partially solved the issue because if I were to revert the settings back to what they were before, the FPS begins to drop as low at 50 FPS with lots of fluctuations. However, I would like to figure out how to improve the general performance of the card even with these new settings enabled as I'm now getting the same performance as my previous card. I just find it strange how the performance of this card is dependent on the Radeon software, meaning that the performance would go down once again if Radeon software were to crash while playing a game.

In any case, I hope that this thread is helpful for anyone who might come across it in the future.

 

That is good to know, it really sounds like issue with the driver though as Radeon drivers and software should definitely keep it boosting to normal frequency without effect to FPS.

I don't know much of AMD GPUs sadly, Last of mine was Ati Radeon, I think it was 9700 or something and it had lot of issues on software side of things. What I have observed though is that as AMD GPU software team is rather small compared to NVidia they seem to have sometimes bit longer fixing time for the issues, which is a shame.

Anyway as issue sounds like it is affecting people, they perhaps will bring fix at some point.

Also one thing that came up to my mind is power profiles, in Nvidia, there is Optimal power, Adaptive and performance profiles. I don't see huge difference between Adaptive and Performance, except Performance is putting out loads of heat as it is not letting clocks drop down, I guess that is bit similar to what you have to do in Radeon software, but maybe there is also power profiles to select?
Also power profiles in Windows and power management settings in Bios might affect the whole picture.

 

I don't see any specific power profiles within the Radeon software but it does provide me with a slider to manually change the power usage... It also appears that this issue happens in a few different games. I tried to play a bit of GTA V last night and the GPU utilization was 99% with power draw of 255W. The game did crash though after a little while so there's that.

What sort of performance are you getting after the new update? Also how many mods do you have installed in the game?

 

Have you tried the Vulkan mode in beam? it fixes the performance issues for me

 

It doesn't seem to be working for me. I get a black screen with the mouse cursor and that's pretty much it.

 

Hm wierd for me it worked yesterday but today it seems to have stopped working but id say try it again later it really helped alot for me.

 

Hey man, sorry to keep bugging you but since you know a lot about this stuff I had one more question for you. I noticed that if I switch to free camera mode and move around the map (far away from the car) I notice that the gpu utilization increases dramatically and even reaches 99% with frame rates going as high as 250FPS! So could there be glitch when I'm closer to the car and driving it around the map (utah) or is that simply the way beamng works meaning that closer I am to the car, there is more pressure placed on the CPU rather than the GPU? For reference, I get around 90-120 FPS while driving around Utah in the gavril pick up truck with no traffic, with GPU util. fluctuating from 30-80% as mentioned in my previous posts.

 

nvm

 

?

 

i thought I was having the issue but my dumbass forgot to close phoenixminer

 

In really old BeamNG version there was some oddities in regarding camera, so it did work like this, in chase view I got certain amount of fps, then I did shift-C to get to free camera and even camera was at same spot FPS did shoot up by certain amount.

If that happens for you, then it might be interesting information for developers who might have and idea then which is the cause of that, but if camera needs to be further away from the car for FPS to shoot up, then I'm clueless, there are no LODs in cars, afaik.

Either way, it must be some kind of bug in GPU drivers though.

 

That's good to know. I was actually thinking it might be due to the focus being away from the car, meaning less CPU resources to be used up by the car and therefore the CPU can process more data from the GPU, resulting in a reduced bottleneck.

 

Code that makes camera to be 'attached' to car might use CPU, but I doubt that in this case that really would matter.

My guess is that something in shader code might be reason or way texture layers work, but in 0.23 version those have changed quite a lot compared to 0.22.

I guess it might be possible to pinpoint by setting shader detail level to normal or low and see how much effect it has, with your hardware it should not make huge change between high and normal and at low fps should be insane, I believe.

2nd would be post processing stuff, things like Ambien Occlusion (SSAO) or bloom etc.

Generally if some setting give ridiculous fps boost, then that feature could be one causing the bug in driver to happen, but this is not fail proof way as if issue comes from way car just is rendered, then you should not notice huge fps increase that is out of proportions.

Also I don't think there should be huge increase in fps when you move away from the car, that is when bug is not happening, these cars are quite low poly and even single car's shaders should not be much to render with your hardware, so my guess is that when there is no fps jump when moving away from the car with some changed setting, then that setting must be related to bug happening.

Well, it is kinda boring to test each setting one by one and see if there is huge change in fps or not and it might not reveal anything, but only thought how to crack why this happens that I managed to get

 

So I tried making those changes to the game's settings but with little to no success. While I noticed some FPS improvements in orbit mode (around 10 FPS, depending on the direction of my camera while the car is at a standstill), the frame rates continue to jump when I move away from the car but only top at around 150FPS despite adjusting all those settings. In any case, I reached out to the BeamNG support team and even tried to replicate the issue, so I'm now waiting to hear back from them.

 

Hopefully they get back to you soon about this.

With 144Hz monitor I have noticed that I don't have enough fast GPU here, but GPU load is pretty solidly at 99% so I'm quite certain that you should not see CPU hitting the limits quite at 150FPS yet, but around 200fps it probably starts to happen as faster the FPS, more CPU is needed for a time unit as CPU computing power required is for each frame, so 120fps is roughly twice of 60fps.
