This isn't the 80s or 90s anymore. Back then, pretty much every somewhat advanced game asserted full control over the computer hardware as the first order of business. Operating systems neither had the means to prevent this, nor did they have the right kinds of drivers in most cases. With proper protected mode operating systems that include usable driver interfaces, this is thankfully a thing of the past. Modern hardware and modern operating systems usually take care to ensure that any hardware acceleration features are exposed in a way that doesn't create security risks. And, unlike on consoles with known hardware, it doesn't make sense anymore to try to talk to PC hardware directly from a game because things like GPUs are so varied and have so much "secret sauce" these days that trying to create custom drivers is an exercise in futility.
