degen Zero problems in the full screen mode AND in the borderless window mode.
The discrete mode is set in-app. E.g. https://www.acer.com/ac/en/CA/content/predatorsense
The model # is PT515-52-73L3.
Bought it here: https://www.amazon.ca/Acer-Predator-PT515-52-73L3-i7-10750H-Dual-Channel/dp/B08CNLPDXV/
I might be lacking the technical skills needed to install linux and figure out how to switch to discrete mode in linux.....but I'm not opposed to trying to figure it out if there's a high chance of success
