insanely poor application framerate (the app itself)

[Hungermantwo]

tried every option in the menu, currently running windows 11. The app itself seems to fluctuate from 48-55 fps, with the counter saying 51-56 or two random numbers that change constantly. This is regardless of whether its focused on the desktop or specific application. The actual shader application runs as expected, its just the app itself that stutters and has a crazy inconsistent framerate.

+1, also seeing this happen to me. Seems to fluctuate between 45-55 fps. I have the FPS set to vsync, and using on a 144hz screen.

Hm not a lot to go on here, I assume you have decent GPUs and a recent Windows 11 version.
if you have both iGPU and dGPU make sure ShaderGlass runs on dGPU (force through Windows settings).
When you enable Flip Mode, title bar will show [input fps] -> [output fps]. To go over 60fps, you need to put SG over high frame rate content as otherwise Windows will throttle capture.
Try disabling any frame limiter or similar software, and resetting GPU settings to default. Also, try high performance power plan.

Did anyone find a fix for this? im having the same issue. Jittery frametimes when my monitor is set to both 60hz and 144hz. Real shame as it looks great and does just what im after.
