Hi,
I have a suggestion to make especially useful for NVIDIA users. You probably already know of Nvidia Inspector. It is a software that allows creating custom nvidia profiles or modifying existing ones. It is pretty useful, it allows the user to force anti-aliasing, anisotropic filtering, vsync, ambient occlusion etc. But the most useful things in my case are anti-aliasing, SLI and ambient occlusion. Sometimes predefined NVIDIA profiles are missing some important components. Most importantly compatibility bits. There are already some compatibility bits which you can find online that allows you to enable SLI support, force SGSSAA/MSAA anti-aliasing and that kind of stuff. My suggestion is it could be pretty useful to add these compatibility bits and other nvidia inspector tweaks to pages. What do you think?
Some compatibility bits that you can find online:
