Currently there is a fix in Proton hotfix and experimental bleeding edge.
Seriously give this game a shot. It can be overwhelming at first. The team at Embark have poured love into this game and you can feel it. It's such a refreshing experience and so much more than the average CoD.
The balancing isn't perfect and questionable at times. There is a bit of a learning curve. You'll certainly run into sweats but hopefully as new players jump in, it will balance out. The game is creative, dumb, and fun all at once. Not the highest game population on pc but it is rock steady between 15k to 20k everyday. That doesn't even include gamers on console. Worth a shot since its free.
