Wotlk - Low fps and stuttering

Hello, so recently I've been experimenting as the title says low fps and stutts with Wotlk client. I've a fair good pc that can run Retail (Shadowlands at the time) on high quality with no problems. I'm using the new Legions/Wod models from this post https://forum.warmane.com/showthread.php?t=342158
Also I tried deactivating all my addons with no success. I leave my pc specs just in case:
Motherboard Gygabite H410M H
CPU: Intel-core i5-10400F 2.90ghz
Ram: 32 gb
GPU: Nvidia GeForce 960

Should I delete the new models? Anyone has gotten any problems with them?

Try using Large Address Aware on WoW.exe https://www.techpowerup.com/forums/t...-aware.112556/
and if that doesn't help try disabling hardware cursor

Disabling hardware cursor worked like a charm! Thanks a lot!!!
