Nvidia abandoned gaming in 2020 and never looked back
4K monitors with high refresh rates are expensive and poorly supported (even cables are hard to source)
The industry itself gave up on actually trying to do 4K and went for AI upscaling and interpolation
Several places, namely California, put outright bans on maximum power draw on new PCs. 4K regularly blows past it with the GPU alone
Game studios are imploding under the cost of 4K content creation
