Performance since Patch 6.0 is terrible.

I've never had great performance in Space Marine but since the patch I've only been getting like 30-40 FPS, even down to 20 when it gets busy. I've fiddled endlessly with settings and none of them seemingly make a difference.

My GPU usage never gets higher than 45-50% and my CPU hovers around 60-70%.

Currently I'm using the same settings as my friend as he gets 50-60 FPS, his specs are:

Ryzen 5 5600X
RTX 2060
16 GB RAM

My specs are:

Ryzen 7 3700X
RTX 4070 Super
32 GB RAM

There is definitely a bottleneck with my CPU but it shouldn't cause this bad of an issue right? Drivers are up to date for my GPU.

Any help would be greatly appreciated.
