There is a possible fix for this by doing the following.
Go to the game's folder.
(STEAMS DRIVE):\SteamLibrary\steamapps\common\Usurper
Edit the options ini file with the following.
CreateTexturesOnDemand=0
Save and close the file.
If this does not fix it, try turning off in-game vsync, this solved it for multiple users.
The options ini file might get re written every time when I update the game so I will try to adjust this.
Cheers to "Jay-bat green" on our Discord for the fix!!!
