DPI Scaling issue windows 11

Hi Community!

I have a retrobat setup on my mini pc connected to my LG OLED 4k tv. to make text legible windows of course set DPI scaled high, i found %250 the sweet spot. Issue is i noticed games run slow, im assuming something gets confused when transitioning from windows to retrobat.

When i changed DPI scale to %100 and launch retrobat the issue is gone! I clicked around on custom DPI settings for retrobat under properties but wasn't sure the correct settings to make retrobat launch in %100 and ignore the windows global setting of %250.

Thanks all!

Bump for any ideas?

Yop,

If beyond 100 you have problems with emulators then most certainly Retrobat can't do anything about it.

I invite you to search on Google if there is a method to change the DPI by script or alternative software.
If possible, perhaps automatically load by script at 100dpi when Retrobat is running and when retrobat closes automatically return to 250dpi.

Hi, if you right click the retrobat.exe and go to Compatibility and try to change your DPI settings there, is that perhaps working? Click "Change high DPI settings" at the bottom.

I have sometimes problems when opening .exe files that they open too small, so I override the DPI settings and put them to System (Enhanced). I use an LG C2 4K 77" OLED. But I never use the HDR mode in Windows or gaming.
