I have a Commodore 64x PC clone, its awesome and I recently upgraded it as a Covid lockdown project. So I have decent CPU and memory but only Intel HD onboard graphics. There's no graphics card going in my rig :( TBH 2D Games have generally worked quite well with some tinkering and as Proton has evolved, more and more games are working albeit on lower graphics settings. Horizon Chase Turbo however is the first game that worked perfectly after installing it including with my Stadia (RIP) controllers and I'm loving it!
