Major bugs on U8

Im having major bugs. The game is basically unplayable. I have an RTX 2060S with an i7 8700k and 32 GB ram, using the valve index. The fire balls can't be thrown they just float in the air. You can't combine both hands of the same or different magic as was hyped. Gravity is relatively buggy but somewhat usable still. Imbuing isn't working all that great either. Whenever i set something like infinite mana or invincibility it reloads after every death. But the biggest problem which makes this unplayable is that it's way too intense on my card. The whole picture is stuttering. Frames drop to nothing if I do anything but low settings, no MSAA, 1.0 resolution and no SS. I'm kind of disappointed. I mean if dude needed more time he didn't have to announce for now. What's going on here?
