I think I get the idea. For retro games, I can spoof a smaller monitor (I currently run an ultra-wide). I can use FSR for resolution scaling even on games that don’t support it. If I was making a DIY gaming console or a dedicated gaming PC, I can see it’s usefulness. I’m not sure I need it for my “daily driver” though.
Those that have more experience with it, am I missing anything?
There are some short falls with compositors, which we see quite a bit in Linux gaming and vsync. Maybe haev a look at these two videos:
Yea, I’ve seen this guy’s videos. He kinda rambles a bit but eventually gets to the point. As I said, I can see it’s usefulness for a dedicated gaming rig. One downside though, I’ve learned you can’t cut-and-paste from the desktop to a gamescope session. So, for example, account login passwords have to be manually entered from memory as opposed to copying from your password manager.
Like he said in one of his videos, there’s no point in installing it just to fix a problem that could otherwise be worked within the tools you already have.
I think the perfect solution … have the Gnome or whatever compositor you use better handle dropped frames. The Wayland protocols are there. Just a matter of the compositors supporting them.
For myself … not a fan of handing off to a different compositor (because now I have to run 2 to get the game performance I want). So I try to exercise patience. Gamescope and Gamemode are kind of tuning I tinker with as well.
Now, gamemode, on the other hand, was a totally different animal. Adding that was like a graphics card upgrade. Significant performance jump on my PC.
