But will it run Crysis?

Ever tried gzdoom? https://zdoom.org/downloads

Combine it with brutaldoom v21 https://www.moddb.com/mods/brutal-doom/downloads and set settings to everything cheap and crispy (I use cheap for the sake of it, I like my processor to remain cool, all my machines are fanless because silence is priceless)

Again remove all the fancy shits (antialiasing on "pixel art" is just ugly). I cap the framerate at 60 fps, but that's just me

Tactically speaking, it's fucking great, there are even vehicles such as tanks and helicopters, but that's not what this is all about; this is all about "corridor pistol shotgun full auto and nades"

Now granted, it doesn't get the versatility of an emulation (read, one "rom" works everywhere)

My half brother played competitively back in the days before the internet. I forget the name like dbs or something.
