Just a small thread to point out an issue that comes with the jerky FPS of sam when using Direct3D, today I found out that OpenGL does not support 1080p at 144Hz, I think neither Direct3D does and that's why the display was so screwed and laggy even if it feels like 144 is working.

I saw that because today was the first time I played a game on sam with a 24" FHD 144hz monitor.

If you don't mind 60hz or do not own a 144hz monitor, you'll be fine with FHD, if not, the solution is to lower one resolution.

Additionnal note: do not try 1440p with sam, the game absolutely can't bear it at all, it may even crash.
