nice! Sorry, my monitor don't go to that resolution, so I have no idea.

@chris_l, I'm actually running at 1440p using the graphics packs, yet I get extreme blur when the window size is set any larger (in my case 3840p). My only workaround is to set my xrandr resolution to 1440p before launching CEMU. Any idea why this would be needed?

@vectro, it sounds like you aren't using the community graphic packs.

Install them, and activate botw->graphics->resolution and set as active preset the resolution of your monitor. You'll get better quality than letting your monitor to upscale the default low resolution of the game.

For anyone getting blurry graphics in BOTW: Set your xrandr resolution to match exactly the resolution set in CEMU, and then run the game full screen. I tried changing the wine settings to avoid this as well as the CEMU settings, with no luck. It seems wine doesn't upscale nicely. Hope this helps.

I understand what you mean, but those variables are not there because they are, they are there to get the maximum performance possible. If you want more information about GL Threaded Optimizations I leave these links:

mesa_glthread is the equivalent for AMD / Intel and it is recommended to have the vsync disabled, but I don't know how well it works, also a detail is that apparently GL Threaded Optimizations can decrease performance if your CPU is 100%, in my case I get these results:

I found a good reason for R600_DEBUG=nohyperz. It allows users of AMD Polaris cards to play botw. So I'm going to add at least that one the next version.

Still checking about the other two.

Well no, I'm not going to blindly copy everything cemutil does, I need to know whats the purpose of adding them.

Particularly, I don't agree the inclusion of vblank_mode=0.

That flag disables vblank, and disabling it can produce tearing. Someone with a weak video card can benefit from that, but the people with more capable cards could get unnecessary tearing.

That is, if someone wants to play with that flag on, they can apply them themselves.

But, if you know what the other flags do, and they are useful, let me know, and I will check them.

You should also add the environment variables __GL_THREADED_OPTIMIZATIONS=1, mesa_glthread=true, R600_DEBUG=nohyperz and vblank_mode=0 to the file, so it would be on par with the Lutris and Cemutil script

@barfin, in my previous comment I mentioned that I was working on the shared fonts part.

It took me a while because I wanted to download the fonts from an official source and I had to find a link for that (that script its just getting the fonts from a zip file in their own repo)

Anyway, its done now.

barfin commented on 2019-07-28 20:44

exactly shared fonts cannot be downloaded in cemu using wine and this script does that i wish you could just add them so i would use this aur package instead of that script
