NVIDIA GeForce RTX error code 43 on Windows 10 version 1607

[halohalo]

I thought driver security updates resulted in drastic FPS drop in P3R. But the true answer is UE4's shader compilation issue is the main reason. So I think I have to edit engine.ini carefully to deal with it.

Just like R545, Quadro GPUs users can use R550 by simple modification. However, NVIDIA app will replace control panel in near future. Unlike NVIDIA control panel, I think new NVIDIA app will not be compatible with 1607 anymore.

About UE4's shader compilation stutter issue in P3R, obviously R550 drivers have better performance than R535 drivers. Now I am using 552.61 and trying to find an ideal solution.

[halohalo]

Finally I think I've solved the shader compilation stutter issue in P3R. I edited dxvk.conf and enabled following options.

dxgi.hideNvidiaGpu = False

dxvk.numCompilerThreads = 0

 

So dxvk-2.3.1 can use all CPU cores for shader compilation. And I am satisfied with the result. However, the Adaptive Sync in 552.61 or 552.55 no longer works with dxvk-2.3.1 or dxvk-async 2.0, so I have to edit NVIDIA control panel and close Vsync for P3R to make Adaptive Sync work.

Redesigned NVIDIA driver download section doesn't contain driver type option, which means it can't show non-DCH driver download links of R470 or earlier driver branch when DCH driver is available.

do you guys think it would be technically possible to get a windows 10 driver for the 3080 running on windows 7 SP1 x64 (since latest driver for win7 is version 475.14)?
i successfully modded the .inf file, changed some imports with CFF explorer, disabled driver signature enforcement, but nvlddmkm.sys still does not load,
since i haven't figured out the hex edits yet.

[halohalo]

If you checked nvlddmkm.sys for Windows 10, you should know it is completely different with nvlddmkm.sys for Windows 7. Just install 475.14 for Windows 7 when you use 3080 on Windows 7 SP1 x64. 

[halohalo]

Now the original driver download section and advanced driver search will be redirected to new driver download section. So it will be difficult to find standard style driver released before 2022 for Windows 10 1511 and 1507.

[halohalo]

Finally, I found an ideal UE tweaks from the web page.

So I modify Engine.ini and successfully reduce stutters in P3R.

[SystemSettings]

D3D12.PSO.DiskCache=1
D3D12.PSO.DriverOptimizedDiskCache=1
r.TextureStreaming=1
r.ShaderPipelineCache.Enabled=1
r.ShaderPipelineCache.StartupMode=3

 

However, modifying dxvk.conf and using R550 driver are still necessary. Now I am using latest 553.00 Vulkan beta driver.

[halohalo]

R470 ended at 475.14. R565 belongs to new feature branch, so it will be replaced by next driver branch which supports Blackwell GPUs released at 2025. NVIDIA still provides new security updates for R535, but it is a matter of time that NVIDIA will completely remove compatibility with old versions of Windows 10.

[halohalo]

When I use Steam game recording, OBS Studio 30.1.2 or latest OBS Studio 31, the volume of m4a or mp4 always becomes -10 dB.

The issue occurs on 552.93 and 553.51, but 538.49 is not affected. I've tried P3R (Vulkan) and P5R (D3D11), so I think R550 has same problem on 1607. However, I also found that if I failed capturing game video, the weird volume issue disappeared. I didn't notice the issue before because re-encoding fixed it.

NVIDIA released latest security updates 553.62 and 539.19 for Quadro. But NVIDIA is not ready to release latest R570 driver before the release date of GeForce 50 series, so there is no latest security updates for GeForce on Windows. Even the information of upcoming updated driver version is unavailable.

[halohalo]

The minimum version requirement of driver branch R570 is 1803, because 1709 and earlier versions do not support the function IoOpenDriverRegistryKey. Besides, NVIDIA no longer supports 21H2 for professional graphics cards. Latest HDA driver is still compatible with 1607, but R570 no longer provides 32-bit HDA driver.

I did more tests on different driver branches.

556.12: CUDA, OPENCL, Vulkan are broken, but OpenGL, D3D9.0c and D3D11 are fine.
561.09 and 566.45: Installation completed without error message, and NVIDIA control panel works fine, but 1660Ti shows blank screen.

I tried to overwrite OS version to 1803 instead of 1709 and bypass related check codes. Now I can run simple Vulkan demo using 556.12, but Furmark2 benchmark still crashed. I guess if I want to run OPENCL in 556.12, I have to find out a solution to make CUDA 12.5 work first. Besides, Vulkan supports NVIDIA Optimus, so I can run simple demo using 566.45.
