Photoshop is extremely laggy on high-end system
Trust me when I say I've tried EVERYTHING.
This includes:
- clean installing Windows 11
- installing the latest studio drivers
- installing older/factory drivers
- using Creative Cloud Removal Tool and reinstalling Photoshop
- increasing the Performance settings to max (RAM usage, cache levels etc)
- laptop's cooling is perfect - vapor chamber heatsink, new thermal paste, doesn't get hot or throttle
- Windows performance mode
- turning off hardware acceleration (not a real fix)
For reference: Intel i9-13900H, 64GB RAM, 1TB SSD (7000mb/s, brand new), Nvidia 3500 Ada 12GB
All of these only for Photoshop to run like a turtle. This is system wide - brush is laggy (it's not the smoothing setting), selections are laggy, creating shapes is laggy, scrolling/zooming is laggy etc.
I have a PC with almost the same specs and same settings, and Photoshop runs fine. No issues there.
