Gotcha. That should be right at the edge of where you may see some benefits from memory, but it certainly shouldn't show better performance across the board.

I don't have that exact spec available, but I do have a 3080 mobile I'm dual booting, so I checked a few games I had installed or were small enough to conveniently download and boot up on both.

Couple caveats: Linux audio is outright broken on this laptop, which is a bit of a dealbreaker and a real bummer. Also, it's running Win 10 on the Windows side, not Win 11, which is one of the reasons I'm dual booting it despite the speaker audio being busted. I don't think that impacts performance either way, though. Also also, man, am I sweating now. This thing is a fantastic space heater when cranked up. Also, also, also, all of these are maxed out at 1440p, for reference. RTX on, DLSS on at max settings where available, since we're testing for Nvidia feature performance as well.

So, spoiler alert, this went how I expected it to go:

Quake II RTX: 44-46fps on Windows, 40-43 on Linux. Basically the same. Linux was more stable and frankly, if I didn't have a FPS readout I wouldn't have thought to lower settings for more FPS, it felt so smooth.

Bloodstained RotN: waste of time, it has a 60fps cap and it runs identically on both, down to brief stutters when changing rooms. I had it installed, so now you know.

Lost in Random The Eternal Die: Super optimized game on Windows, shockingly much worse on Linux. 125-135 fps on Windows, just 110-119 on Linux, and more stuttery. Was not expecting that.

Abyssus: Unreal 5 game. Another surprising Linux loss I wasn't expecting. 70-120 on Windows, but a bit stuttery, but only 53-77 fps on Linux. Windows was more stuttery this time and showed some glitches I didn't get on Linux.

Lego Builders: Raytracing showcase, pretty even. 45-60 on Windows, 53-55 on Linux. Again smoother on Linux despite lower max FPS.

Orcs Must Die Deathtrap: More Unreal. 36-43 on Windows, 33-38 on Linux. Another case where max fps is lower but it feels a bit smoother on Linux. You'd definitely crank settings down on this one for both OSs.

So yeah, like I said, no surprises. Linux is generally a bit slower in terms of max fps, which is expected, but a couple of games really don't like it. Proton tends to fix some stuttering and often that offsets the lower max fps loss. So, big things we learned: Proton is really good, I wish ASUS had better Linux support for audio and Linux gaming is very, very doable but not perfect. I haven't changed my mind much since the last time I tested this sort of thing.

Hey, if nothing else, that's a great list of games and they all run fine on Bazzite, so if anybody is looking for game recommendations I stand by all of them.
