PoE2 crash, lag and screen tearing fix
I know this is a build sub but you can't build if you're having issues with the game working properly.
TLDR:
Open file>PoE2>properties>compatibility>[✓] run program in Windows 8> [✓]disable fullscreen optimizations>click apply>click ok>have fun
This is for anyone suffering from constant crashing, lag and screen tearing like I have been since release despite running an upper mid tier R9/Vega64 nitro+ rig with 32GB RAM. I'll keep it short: go into the file folder, open properties on the PoE exe and check the box to run PoE in compatibility mode for Windows 8, after that disable fullscreen optimizations the click apply and ok.
Whenever I did that the game ran like a dream. You may have to tinker with your settings in game but I hope this helps someone. I had been dealing with nonstop crashing and other technical/optimization issues since release and after doing that I've only crashed once today after playing for 6 hours. Have fun!
Sidenote: If you are afflicted with the 24H2 Windows architecture bug this might not work, but it still doesn't hurt to try.
