I can see why you'd think that, but what you fail to understand is that valve is not the only one working on proton, and valve themselves did not even make DXVK. Those are free and open source efforts and valve even pays external devs to commit to that software. I'm telling you that DXVK itself is not going to give a boost to graphical performance because it literally cannot, those are extra instructions that your GPU has to perform in order to send out frames.

Directx to vulkan translation is exactly that, translation. It receives directx calls and translates them to vulkan. For one, it has overhead, two, if the game is optimized, it is already going to be running at max performance on windows, using DXVK is going to slow the GPU time down because it will have to perform more calculations. No scheduler will save you from that, not even the Linux one, because it isn't something that is handled by the scheduler.

Go right on ahead, I've done the tests myself already.

Keep in mind though that if you are using a laptop, nvidia tends to work better when paired with Intel vs amd for the sake of graphics offloading.

I don't think you understand how this works, I'm not trying to disprove anything, you are the one trying to prove something. You chose 10 very specific games to run these tests, some of them being heavily CPU bound, and state that you are receiving an increase in GPU performance when it is simply not the case. All of these games are also optimized for proton, which does not help your case.

Tell you what, why don't you give something like "Spec Ops: The Line" a test? Halo Infinite? 40k Darktide? Vermintide 2? Dying Light? Hell, infinite and darktide are very popular in the Linux gaming community, I was even one of the beta testers for darktide.

I've been using Linux since before Xwindows existed

Why are you blatantly lying like this? X came out seven years before the Linux kernel was even released. And even then, there wasn't a working system for the Linux kernel when it was released. Keep in mind I said DAILIED Linux for 18 years, I didn't say USED, I've been using Linux for 27 years now. I actually remember a time when Linux was not an operating system that people would use to play games on.

I'm using my time specifically in the community as an example to show that this is not the first time I have heard this. OP supplied evidence in ten very specific games here, there are over 12000 games on protondb that are "playable", not even verified. I have run across myself quite many games that run at half to three quarters the performance that it does on windows, and that is absolutely fine.

Telling people that using Linux will get you a "free performance boost as much as 17%" when it very likely will NOT, will create a lot more angst towards the Linux community than it already is. The elitists are already doing that for us, we don't need more of it.

We should be pushing people towards Linux for digital privacy+security and free software, not cherry picked performance boosts.

Yes, I very well recognize the black magic sourcery of proton and wine, but you are sitting here and trying to tell me that proton is somehow going to make your GPU somehow physically push more calculations per cycles just because it is running Linux. Not even giving me the "mesa drivers" spiel which is also BS, as performance is not the main area that the Foss drivers are better in.

Linux is not going to break the laws of physics buddy, I've already said what I said, boost in CPU bound games, little to no boost in GPU bound games. If you're seeing a boost, it's because you have a CPU bottleneck and you are getting it because of the scheduler.
