Get off Windows 7, it's not even supported by Microsoft anymore since 2020
We still get drivers update despite dropped support (check nvidia and amd); There is stil updates every month if you have pro version and ESU subscription you have updates till 2023, and maybe more after, like 2024.
Anyway since sp1 there has been only like two or three important security updates. The rest is mainly internet explorer and windows defender or ms office updates or drivers (which you can upgrade manually with 1 or .inf files, if you ever have encounter a single problem on this OS :) )
In two month of win 10, forums had more problem threads than the whole history of windows all pute together...
Anyway since 2009 any game using dx11, vulkan or opengl can work on windows 7, unless you do something specific to no make it run, like using dx12 (and still using dx/vk can allow you to run some title like the last Hitman for instance).
It is different from xp which was 99% 32 bit users. Since 2009 everyone switched progressivly to 64bit, so everygame will run forever on win 7. + win 7 pro has the advantage of providing a free VM with win xp license, which allow you to basically run any 16bit program.
And even now some devs that are developping games still somehow support windows xp simply because they use dx 9.0c. The recent Lost Ark use dx 9.0c, which is very old but does a good work if you can code ;)£
high graphics is no more an important point on pc gaming, most of the best games are indie nowadays. So it's quite nice to have the best looking AAA (cp2077) on win 7. Some new game like total war warhammer 3 also use dx11 and run on 7.
On the paper win 7 can run 3 times more games and software than any other windows, may it be xp, 8.1, 10 or 11.
I'm not even supposed to be able to run win 7 on a 5600x ryzen, but it works perfect with the modified usb3 driver.
