HDR display poor performance
I recently bought a display capable of HDR (LG 29 ultrawide) . Unfortunately, with this purchase the performance problems in lightroom classic started. Everything is now slow. From the interface to the dropdown menus. Even when i try to open file menu, it flashes white.
I tried disabling free sync but with no luck. Tried updating nvidia drivers, no luck.
When i edit a photo and i make changes , the image showed on the screen is not updating in real time. I have to click on it to zoom and then it updates. Even the zoom is laggy.
Without HDR enabeled in windows settings everything works well, but I lose all the advantages of the hdr screen.
This problems occurs in photoshop app too.
I post all my pc config from lr settings
