My PC (with 6 cores i7 5820 K CPU and 3.3 Ghz and Nvidia 950 GTX Video card, Cintiq 22HD ) using Windows 10 crashes each time Painter 2021 tries to optimize for Graphic acceleration. Also, cannot use AI styles as this restarts my PC each time. Painter was reset, uninstalled and reinstalled without improvement. Ran Painter 2019 and runs Photoshop 2020 without problems. Any suggestions would help. Thanks.
Hmm, AFAIK it should work with that GPU here are a couple of ideas:
1. Check if you're on the latest driver for that card. In this case I would ensure I'm using the vendor-supplied driver (i.e. downloaded from nVidia.com) as opposed to the 'automatic drivers installed by windows).
2. If you haven't rebooted in a while, definitely do that (some video cards update their driver without a reboot, so it's worth trying)
3. Try the Brush accelerator test again
In terms of the AI Style issue maybe we can start with the GPU problem first, then circle back and troubleshoot it...
Just a guess-disconnect your Cintiq 22HD and try again. Ialso assume you have read and done all this- support.corel.com/.../360025425073-Painter-2020-Tuning-GPU-settings-for-optimal-Painter-performance
