Yes, cpu load is lower. Maybe it's an specific dosbox problem with the game menue + loading screen & vsync / double buffering? Due to this gfx effect in the background? All my other games just work fine.

Thank you. Tearing is gone, but now performance in Jazz Jackrabbit's menues and loading screen is really laggy for openglnb / pp in both windowed and fullscreen. Gameplay is fine. Acts exactly like surfacepp fullscreen with double buffering on now. btw i have to correct my previous comment, that …

unfortunately i dont know how to apply the patch - i just use Yesterplays ECE. 😒

Turning on double buffering with surfacepp output results in quite a performance drop in fullscreen. very choppy main menu etc (Jazz Jackrabbit). yet windowed is …

In fullscreen yes, windowed its fine.
