Trent2501: Similar issues here, although the system used has a 9xx series card. During some spell animations the game tanks completely (especially illusions like Mirror Image). So it seems to be an NVIDIA specific issue.
What is really weird is that I played it around release on the same system and do not remember any issues there, like the OP said. So what did they add since then that results in so much problems?
NVIDIA specific issue ? that sounds very logic, and maybe in a way NVIDIA has many issues , but the developers should be able to test it on many systems , otherwise they should not develop games, if you want to make sure lots of gamers will buy your game and have it run properly on their system.
You cant go on developing games that only run well on anything as long as its not Nvidia,
or they should mention: DO NOT use Nvidia, if they would simply add that it runs a charm on ryzen or similar but Nvidia should be avoid cause it could cause problems, many problems would be solved.
Anyway thats the problems with todays hardware , in the old days a game ran or did not ran on a certain system,
today with all the click n play create a game tool you have too many problems, games seem bloated, resource heavy even on high end systems , the biggest problem is the $ they ask for it :D 30 to 60 even 99 USD or euros :D
In the old days when we bought a game we looked at the system requirment on the back of the box: min and recommended..... never had any problems , the game ran or did not ran or had some lag, then again back then there was little choice in GPU.
