My Hardware:
4930k @ 3,8GHz HT on
780Ti @ 1124 MHz Ingame
16GB RAM
Software on SSDs (Win/Software)
Start Faction - 185-190fps
Anaconda arrive - 85-90 fps
Same fps over a long distance
at a short distance to the fight - 60-70 fps
GPU-utilization: 67-82%
CPU-utilization: of the 12 cores use 6 75%, 4 50%, 2 5%
I hope it helps
I guess that first 6 cores with 75% utilization are physical cores, the others are logical. It seems that there is no noticeable difference between i7 4930k and i7 2600k, which probably means that the game is not optimized in terms of performance.
Have you checked your GPU utilization? My guess would be that it drops to about 70% when you get the lowest frame rate.
Thanks for your post. This means that there is no special need in CPU/MB/RAM upgrade yet from Sandy Bridge.
