NVIDIA released 474.88 only for GeForce RTX 3050 GPU in 2024.

If you compared INF files for Windows 10 and Windows 7, you will find the answer. Unlike Windows 10, the driver for Windows 7 only supports GeForce RTX 3050 Laptop GPU for one pc maker. GeForce RTX 3050Ti Laptop GPU was launched before driver branch R470, so only users of Windows7 can find out the truth. But it is difficult than discrete graphics card because there is no universal INF file for laptop GPUs.

I've checked all INF files in 475.14 for Windows 7, and nvlai.inf already contains GeForce RTX 3050 Laptop GPU so I think there is no need to modify INF file. The most interesting thing is official advanced driver search and we all know 3080Ti laptop, 3070Ti laptop, and 3050Ti laptop are not supported, and I found no information about these GPUs in INF files. But the release notes contains 3050Ti laptop since 473.04. In fact, 3050Ti laptop GPU was launched before R470, which means the wrong information exists before 2022. 3080Ti laptop and 3070Ti laptop use same section number, and 3050Ti uses unique section number. If these GPUs are supported, I think finding the correct section number in nvbli.inf is the first step. When I found the correct section number for 1660Ti in R410, no one knows 1660Ti can work with driver branch R410 on Windows 10 1607. If users can prove the correct section number exists and the installation is blocked by error code 43, then modifying nvlddmkm.sys will be the difficult next step. However, maybe the true fact is there is no correct section number for these GPUs. One more thing, 475.14 for Windows 7 supports 3 variations of GeForce RTX 3060 Laptop GPU, but the GPU has four variations.

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.

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.

Intel no longer fixes security vulnerabilities for 6th gen processor graphics. Besides, Intel dropped support for 7th gen processor graphics at March. https://www.intel.com/content/www/us/en/support/articles/000005733/graphics.html

Intel's Wifi x64 driver 22.160.0 and later require new functions, so you need Windows 10 version 1803 x64 or later instead of Windows 8.1. If you want to try 22.150.0 or earlier, you have to check compatibility first and make sure it doesn't use functions which don't exist in Windows 8.1. Besides, using old WiFi drivers with security vulnerabilities is not a good idea.

AMD supports POPCNT and SSE4a at same time, but someone tried installing 24H2 with Athron II X4 605 and failed. NVIDIA has same limitation beginning with driver branch R555. https://nvidia.custhelp.com/app/answers/detail/a_id/5554

I tried to replace Lindy 41062 DP adapter with Cable Matters 102101-BLK (VMM7100). The result is VMM7100 can't support wide gamut when using Intel API HDR. Besides, obliviously the new DP adapter has same problem like Lindy 41062 DP adapter, so they can't transfer lossless compression audio when playing UHD Blu-ray discs on PC. Latest ROG STRIX Z490-F GAMING BIOS 3001 including the patch for the LogoFAIL vulnerabilities broke the compatibility with Lindy 41062 DP adapter, so I need a new DP adapter to replace it. But DP adapters using VMM7100 are worse than my old DP adapter. Intel's new WiFi driver can't work on 1607 because it uses new functions from 1803, like IoGetDriverDirectory.

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.

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.

My FurMark2 benchmark score using 552.55. https://www.gpumagick.com/scores/show.php?id=177863 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.

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.

Anyway, I don't think 1607 has any chance to run latest Blackwell GPUs, but only time can prove it.

My FurMark2 benchmark score using 545.84. https://www.gpumagick.com/scores/show.php?id=177195 NVIDIA added new codes to check Windows version during loading driver, so I modified the original requirement then 1607 can use R545 drivers, which means Quadro and Geforce Turing GPUs with NGX may use super resolution in latest VLC media player. For Quadro Turing users, the modification required for nvlddmkm.sys is quite simple. But R545 drivers no longer have security updates, so using R535 drivers should be better.

The minimum OS requirement of latest Intel audio driver 10.27.0.14 becomes 1809, so installing the driver on 1607 requires INF modification. Another problem is 24-bit audio output over HDMI may require Intel's control panel.

Windows 10 21h2 home edition reached EOS, but MS didn't block installation of CU by SSU or remove support for Core edition.

What I've told you has nothing to do with debugging, I can't teach you the answer you need because I am not a programmer. Instead I told you the solution I used, so you can run IDA and hex editor to modify the driver. Officially the minimum requirement of Quadro DCH driver is 17098. That is why 1803(17134) is required. But old minimum requirement in standard driver still works so Tuning GPUs still work on 1709 with DCH driver. If GeForce DCH driver requires 1803, I think 1803 should be enough for Ada Lovelace GPUs.

Did you make 3070 working with R510 and later? If you can't make 3070 and 4070 work by modification, I will guess NVIDIA uses different way to prevent GeForce from working on old version of Windows. Good luck.

Latest ME firmware 14.1.72.2287 broke the compatibility with Batman: Mask of the Phantasm UHD Blu-ray and resulted in noise and choppy playback at specific scenes. Although it is possible to downgrade the firmware on my ASUS ROG Strix Z490-F Gaming, it is still difficult to fix the issue because I can't find a simple solution. I tried using different sound card, reinstalling or updating audio driver or graphics driver, and none of them worked. Finally I solved the issue by switching off the power supply. Anyway, I think putting PAVP in the firmware which requires security update every year is a terrible idea.

OBS Studio 30.1.2 can do Vulkan game capture with FrameView enabled by using display capture instead of windows capture. But February security update of NVIDIA driver still resulted in performance hit when playing P3R.

It seems that latest dxvk 2.3.1 and Vulkan driver 1.3.280 from R550 solved the performance hit issue in P3R on Steam when I use 538.49. I also tried using 474.82 but R470 is not compatible with Vulkan 1.3 so replacing Vulkan driver didn't work on DX 12 games like P3R. Intel's graphics driver for 7th-10th Core processors also supports Vulkan 1.3. Unlike NVIDIA, Intel and AMD have 8 driver files related with Vulkan.

Intel released ME drivers 2413.5.67.0 to replace old 2141.15.0.2511. Latest Intel graphics driver 31.0.101.2127 results in blank screen with audio when I use PowerDVD 22.

Latest Nier: Automata on Steam offered two EXE files. One for old Windows without Windows HDR, the other one only works on Windows with Windows HDR. Without dxvk, the Windows HDR version only shows black screen with BGM. Although the Windows HDR version works with dxvk, Windows HDR can't be activated on 1607. Persona 5 Royal on Steam requires SetThreadDescription. Unfortunately the kernel32.dll of 1607 does not support the function and there is no utility like VxKex. So the game can't run on 1607 without modification.

R545 and later no longer work on 1607. I've tried modifying R545 and R550 by overwriting OS version in nvlddmkm.sys, but only got error code 37. Now I am using 538.49. Because 1607 is too old to support latest DX12, I can't start Persona 3 Reload on Steam. So I have to use vkd3d-proton 2.12 and dxvk 2.2 to start the game. However, I can access digital art book and OST without converting to Vulkan. I think the game crashed because 1607 does not support ray tracing. Besides, latest OBS Studio 30.1.2 no longer works on 1607 because obs.dll uses isWOW64process2 function instead of isWOW64process, so obs.dll can't work without modification.
