If CDPR is reading those forums, I think CDPR really needs to up their game in the QA department ... the 4,.01 patch has broken many things like performance in general since fps in now more 38fps and you can forget 60 fps, RT is unusable, controller support is wonky now for some reason and DX12 just crashes randomly.

One would think CDPR would learn from their mistakes with Cyberpunk 2077 but it seems that .. nope ... let's make the same mistake over and over again and antagonize an already flammable gamer fan base.

I don't think they do, i send bug ticked, wrote here, on steam and W3 forum and they still didn't fixed biggest Memory Leak after 95% GPU VRAM overload issue and even DX12 low CPU Usage...

They only made poor copy of Nexus Optimized RT Mod settings and implemented it to Performance RT option in graphic settings... that's patefic...

I think performance RT is on no matter what in DX12 once you try it. Either that or they somehow halved performance.

DX11 still works fine and is how I am playing anyway.

my 6750xt lost 30% of performance after this update [dx12] - its first time when patch broke performance on my PC
