Agreed that it needs to be fixed.
The only reason I say that it's bad is because it's not a Massive Multiplayer Online game. The peak player count is 40 in a single match and while the maps are impressive...they're anything but huge. So respecting the relativity of the term "Bad", I'm comparing it to other FPS/TPS' with similar numbers upon official launch and none come to mind that have had this degree or severity of optimization issues.
My specs are:
Processor: i7-8700k
Motherboard: Asus ROG Strix Z370-E
Memory: G.Skill Flare X 16GB DDR4-3200
GPU: Nvidia GeForce GTX 1080 Ti
PSU: EVGA SuperNova 850 P2
SSD: Samsung 960 Evo 1TB
I had the issue on another PC with a GTX 970 so I tried it on my Gaming Rig and also stress tested several other games, Black Desert, Star Citizen, PUBG, ARMA III, Ark, and I've had no issues what-so-ever.
Hell even Ark doesn't have the severity of optimization issues that this game has and Ark is pretty much the industry standard when it comes to complaints about optimization. But again it would only be fair to compare it to other FPS in the 40 man modes.
