Intel GPUs:
- Intel GMA 950 (Desktop: 945GC, 945GZ, 945G; Mobile: 945 Family) or newer, last Intel GPU to support 8.x is Intel HD 5xx series (Skylake; Desktop and Mobile).
- Newer Intel GPUs up to UHD 630 (Comet Lake; Desktop and Mobile) can be also made to work with 8.x, albeit not officially supported by Intel.
- ATI Radeon 9500 or later; last AMD GPU to support 8.0 is AMD RX 4xx series, and last AMD GPU to support 8.1 is AMD RX 5xx series
- AMD Radeon RX Vega and anything up to RX 6xxx series will also work with 8.1, but it have issues with DXGI flip (it just gives black screen, mainly seen on newer Unity games) and Discord/YouTube (driver crashes when trying to play some videos with hardware acceleration enabled)
- NVIDIA GeForce FX 5100 and later
- NVIDIA GeForce 8 series to GeForce 300 series
- NVIDIA GeForce 400 series and later; last NVIDIA GPU to officially support 8/8.1 was the GTX 1080 Ti along with driver version 474.44.
- The Windows 7 version of 474.44 driver will also work on NVIDIA GeForce GTX 16xx and RTX 2xxx series without any modifications.
- But NVIDIA GeForce RTX 3xxx series need this modded 474.44 driver: https://mega.nz/file/fNFlETrA#ZpYUZ35qQfgkyXY7A9-s_QNo2pb5Skrv5RBMeP7dB9Y
