it varies on the game. its either available in-game, only available in the engine.ini config, or needs to be forced through software like drivers/proton.

for example some modern AAA games have a vram usage meter, the lower vram usage means less bandwidth usage. but that meter may not even be accurate to begin with or they hide options like above. in a gacha these commands all affect bandwidth for example
