I've noticed that tuning pressure advance for each different filament makes a huge difference. The Prusa Minis I'm in charge of would leave huge gashes on seams until I tweaked pressure advance for that particular filament. Orca slicer has nice calibration tools for that.
Its honestly really hard to tell with this picture. If you send a better-lit picture of a brim using a lighter-colored filament, we might be able to provide better help!
But something definitely looks off. It looks very thick and very uneven to me, but I also have no real sense of scale with this picture.
In any case, if this is your brim, the mouse ears and other similar proposed solutions won't change anything.
They're actually working on making a version specifically for game developers, but it isn't released yet. There is also a more generic version for developers. dev.bazzite.gg
I've set Lutris to use GE-Proton-Latest as thé default Wine configuration. I do believe you might have some performance improvements over the standard Wine config.
Do you maybe mean Limbo?
