Lightroom classic turns off my 2nd monitor and lags

[7lker]

i have the problem that after a few edits lightroomclassic starts to lag and now it keeps turning my second monitor off and lags too. I don't have a bad computer so I can't explain the situation. I have a ryzen 5 3600x, 16gb ram and a rtx 2070 super. I use the newest version of lightroomclassic 12.0.1 [202210260744-9e008017]

How big is your monitor in pixels (width and height)? Do not tell me inches.

How big are your original images in pixels or megapixels? Do not tell me megabytes.

Are you doing a lot of local adjustments on each image (or some images)?

My monitors are both 1920 x 1080.

The original imigaes are 6000 x 4000.

i do it on each image at the end mostly and then then lagging beginns but somtimes it even starts befor that

Try an experiment ... go to Preferences, then click on Performance, then go to Use Graphics Processor and try each setting (including OFF) to see which one works best
