Performance issues with AMD GPUs

Look up disable deep sleep with more power tool
It stops the wattage and core speed from randomly dropping while gaming which causes stuttering.
I did it and it performs faster than anything I’ve ever seen and it’s smooth as buttwr

 

Thanks I will try that I also found out that setting GPU clock speed to within 150mhz of max 2300-2499 has helped but I am still getting stutters at the begining of loading a derby. I was really frustrated when I wrote that the other day. Thought I was stuck.

 

i have no seen a meaningful increase in performance and often a decrease in most maps after upgrading from a 1060 3gb to an rx 6600, there is often a lot of stuttering, neither gpu or any cpu core is at 100% usage.
the first screenshot was taken at 1080p normal preset. the rest was taken at a mix of low and normal with a bit more detail in the reflections and motion blur as i forgot to change it back to normal.
ive had similar results on different drivers but cannot guarantee that it was close enough to be the same issues.
until recently changing graphics settings did nothing to improve performance or change gpu utilization, though that seems to be fixed.

I have tried the experiemental vulkan mode on both my 1060 3gb and rx 6600 and have never gotten above 20fps if ive managed to load into the map at all (which is very uncommon)

im not demanding help, im just leaving stuff here for the devs to look at.
im getting decent performance thanks to dxvk, but would rather not have to use it as it seems to be causing some instability and texture issues.

 

So I found another thing that helped my situation. Locking the frame rate to somewhere in the low 60's (with AMD Free Sync on) has really helped with the smoothness, it really makes any frame drops a lot less noticeable. Still wish I could figure out the horrible stutter at the first 5 seconds but I can live with that it's extremely smooth after that.

 

Wanted to post my situation here to see if any others are experiencing the same thing and if there's a solution. My system is a Ryzen 5 5600, 16GB 3600Mhz ram, and a RX 6600XT.

In the normal game with ultra graphics on a map like East Coast, USA I hover around the 50-60fps range with mild drops here and there. Once I load in traffic (5ish cars) the fps will drop to 40-50fps. However, in Vulkan mode at ultra settings I sit at the 80-90fps mark and with traffic, I stay above 60 fps no problem. I have the most recent graphics driver and see no other issues on my end. I can also clearly see that in Vulkan mode, my gpu utilization is at 99% like it should be but in normal mode, my gpu sits at 60-70% utilization only. Any solutions?

 

I don’t see the issue here. Use vulkan.

 

the vulkan mode built into beamng is buggy and not stable, ive rarely been able to launch the vulkan mode successfully and have always had worse performance.
im using dxvk at the moment which works very well, but im seeing weird texture bugs with that too.
this person is asking why the game isnt using all of the gpu in dx11?
i remember hearing that dx11 only uses a single cpu thread for sending draw calls (pretty sure that was it) to the gpu, while dx12 and vulkan can use multiple threads.

 

Using an unstable API is not a solution to my gpu only being utilized by 60-70% in the normal game.

So by dxvk, do you mean the vulkan api that you can get online through github? How does that differ compared to the Vulkan API in game and is it any more stable vs the ingame Vulkan mode?

Also, in terms of utilization, how come in other games that run on dx11 my gpu is utilized just fine? I only have this utilization problem with this game.

 

5700G and 6900XT here i cant get my utilization up above 20-30% and it causes my FPS to be 40-50
Id think this system would do better

 

It's not the systems fault if it's not being properly utilized. It's the game's fault and it's what I'm also trying to find an answer to.

If you launch Beam.NG in Vulkan mode, it should utilize properly and then you'll see the real power of your system.

 

DAMN I see what you mean there
I went from the FPS before to now getting 180-200 FPS
a shame the vulkan renderer isnt stable though

 

Sometimes vulkan never crashes and other times it crashes after a couple minutes. Honestly I’ve just gotten used to it because the game performance is amazing

 

In my experience, Vulkan works decently well for the most part. I can play using Vulkan for more than an hour with no problem. However, I notice that after a set amount of time (or due to some random scripts within the game) the fps will tank to the 40's and will likely crash the game after a few minutes or just play horribly. However, a game restart fixes this. Also, if you're changing graphics settings, do it before loading into a map as changing it during the game will crash.

Despite that, Vulkan actually lets us AMD users make full use of our hardware for this game. I just hope the devs either figure out what's causing the utilization issue to occur in the normal game or they make Vulkan stable enough to use on it's own.

 

I tried Vulkan (Windows), selected Italy map, and the map never loaded, stuck at loading forest.
Maybe I had to wait several minutes?

 

Well i dont have a ryzen 9 But i do have a 6900xt if thats any help

 

I suppose 22.12.1 is a mistake, it's 22.11.1, but it's not anymore available, 22.11.2 took the place.

5900X, 6900 XT, 22.11.2, West Coast, Low graphics setting (that's actually the only way to get 140 FPS) :



If you need more feedback, just ask.

 

Yes I saw only 22.11.2 and 22.5.1 for Win 10 & 11 on AMD Site.

@Fluffy Panda Is this request still open? => https://www.beamng.com/threads/performance-issues-with-amd-gpus.82716/page-4#post-1414655
I'd like to help about this AMD GPU issue.

 

Is this what your looking for?
5900x, 7900xt on wcu
Drivers are 22.12.2
