I have a 3080FE with 10Gb VRAM and also run into this issue.
This is not isolated to Star Citizen, but Star Citizen is the most “reliable” way to trigger VRAM exhaustion. It also happens with Elite Dangerous and KSP2 EA also likes to allocate 8Gb of VRAM for no good reason.
To reproduce this I simply spawn at Orison, move to the Kel-to Mall, take a closer look at the spacewhale, take the shuttle to Cousin Crows, if by this point the game is still responsive I fly to HUR L5.
At HUR L5 your trip will come to an end, you can try switch to windowed mode to reduce VRAM usage a tiny bit and you might stick the landing or you will stick the landing after closing the launcher.
Taking a screenshot at that moment will trigger a segmentation fault in libnvidia-glcore.so.
This problem also occurs with the 530 driver, but this driver has other issues. For example Elite Dangerous becomes completely unplayable due to MANY graphical artifacts appearing. Funny enough, it is only ED that shows these artifacts and going back to 525 “solves” the problem.

When I took this screenshot nvidia-smi showed 9995/10240 VRAM usuage.
ED with 530:
Also note the temperature on my CPU going strong at 77, usually around 80 at that moment. There is no CPU usage to be found on htop at that moment either and while playing SC my CPU usually sits between 50-60.
I also have to add that VRAM usage on Linux vs Windows is inflated somewhat, because DXVK/VKD3D need to keep some resources in-memory as well.
Maybe it would be nice to test how DXVK behaves on Windows with Star Citizen, dropping the d3d11.dll in the Bin64 directory should do it!
I have a Zotac Twin Edge OC 3070 and can replicate the issue in Star Citizen and other games with high VRAM usage.
I have tried a number of kernel and graphics driver combinations without any solution.
Arch Linux - Kernel 6.2.2
3 Monitors (two display port, 1 HDMI)
Steps to replicate:
Spawn character in Star Citizen
Get into your ship
Fly to HUR L5 (this location in game has lots of asteroids and gas clouds - my guess is that the asset streaming overloads the VRAM)
FPS goes from 75 to 1FPS almost instantly
VRAM fills completely within seconds
Game is unplayable

Hi @amrits !
I made the video with bug repro. At 0:30 I open the map and fps drops to 10 and never recovers, GPU usage becomes constant 100% but temperature goes down. Opening the map is just the way to allocate a bit more VRAM. It happens without map as well when usage reaches 100%. Also if I open the map when VRAM usage is much lower then 100% everything is ok.
So, I think RTX 3050 mobile is the best GPU to investigate it because I can reproduce the same on almost every modern game.
Ping me if I can do something to help investigate this.
That’s exactly how it is - the best ‘tester’ is Deathloop with everything on the max - under the RTX 4070 Ti after about 15 minutes of playing there is a hiccup as for the RTX 3050 … 100% with 12 GB VRAM. The same e.g. Cyberpunk 2077 on a mobile RTX 3060 with 6 GB VRAM - it doesn’t matter DLSS on Performace = 100% 6 GB already occupied in a moment on the highest settings and drop from e.g. 50 fps to 10 … under 520 drivers turning on DLSS on Performacne freeing a lot of VRAM - but on 525 there is a tragedy - it keeps VRAM busy all the time.
Looks like I do have local repro now on below setup with game Cyberpunk 2077 with default game settings where VRAM consumption is around 6.2 GB out of 8 GB and FPS value ranges from 6-8 during the entire game play.
LENOVO_MT_4810_BU_Think_FM_ThinkPad P1 Gen 5 + Ubuntu 22.04.1 LTS + NVIDIA GeForce RTX 3070 Ti Laptop GPU + Driver 525.78.01
Please confirm if this can be considered as repro so that debugging can be done in right direction.
Can confirm sfjuocekr’s issues with Elite: Dangerous with Nvidia’s newer drivers. Using 530.41, visual artifacts have now rendered it unplayable.
I don’t know if it is the same issue I talk about but at least it’s a nice point to start. I can repro it on my 3050 mobile only when VRAM usage reaches 100% (even for a short period). But maybe 100% usage is not the main reason of the issue but just a good situation for repro and issue can happen below 100% as well, just much less often.
I can confirm the rendering issues in Elite: Dangerous, triangles completely glitch out of position and flicker across the screen with geometry completely deformed, in-game cockpit HUD shows colored backgrounds. Downgrading to 525 fixes this. But I no longer have performance issues since using a 12 GB card with DXVK max memory set to 9 GB (the desktop already allocates 1.7-2 GB, DXVK has some slack overhead from its chunk allocator).
With my previous 6 GB card, it was almost impossible to play with a steady performance as getting in and out of the ship usually overshot VRAM allocations for a very short period of time, ending in high PCI-e bus utilization as render resources seem to have been allocated from system memory - even with DXVK max memory settings.
It looks like some games first allocate resources for a new scene (overshooting VRAM budget), and then immediately free the previous resources. It then looks like allocations are still within the size of VRAM when they really haven’t been for a very short moment.
Downgrading to the 525 drivers immediately makes a lot of these issues disappear. I’m in Arch Linux and just did a downgrade and edited pacman.conf to ignore nvidia package upgrades, including:
Why are people hijacking this thread to report rendering issues? I first reported similar issues here:
It would be better if people replied there or made a new thread.
Please help to test with driver 535.104.05 or latest release drivers for high VRAM usage issue and share feedback.
If a test with 545.23.06 is helpful: I cannot reproduce anymore the problem that I had with Star Citizen as described here, where intense memory pressure would cause the frame rate to drop to single-digit numbers. Now, even when the VRAM is used 100%, the frame rate remains stable.
Since SC has also changed in the meantime, it’s not a very clean test, so I guess it would be helpful if other people also share their experience with other games. In any case, thank you very much for all your hard work!
Shall wait for feedback from other users as well.
Seems like performance issues related to high VRAM usage are at the very least greatly alleviated. Thanks for the fix.
Great news !! Thanks for sharing the feedback.
Yep, it’s for sure much better than before, thanks for fixing it!
Nvidia GTX 970 4GB (545.29.02)
Arch Linux - KDE Plasma (5.27.9)
i can confirm that the above mentioned vram issues still persist on 535.154.05
asus x13 - 5900hs, 3050ti 4GB, 16GB
man. install 535.154.05
vram is being “eaten up” by any application using the dedicated gpu. even a virtual machine is doing that. assigned 256MB will increase the longer the machine is being in use.
as soon as vram reaches 3840-3880MB (when actually 4096MB should be available!) fps drops from 37-40s to 25-30s and stay there until game is being restartet. this applies to Any game.
these drivers can be called bloatware! because their bloating themselfs up for nothing.
tell me if you need any logs or so. thanks!
Just as a followup, it seems like whatever “fix” is implemented breaks if you alt-tab out of a game.
NVIDIA really needs to fix this issue, makes any modern game unplayable. But on windows, VRAM management works perfectly because it relies on the system RAM too and this doesn’t happen with Linux NVIDIA drivers.
