Fps bugg

I've tested two seperate computers with the following hardware:

<b>Computer 1:</b>
Modeboard: <i>MSI X79A-GD65 (8D), Socket-2011</i>
Memory: <i>Corsair Vengeance DDR3 1600MHz 16GB CL8</i>
Cpu: <i>Intel® Core i7-3820 Processor (4GHZ)</i>
Graphicard: <i>Tested with nvidia GTX 680 and nvidia GTX 570.</i>
Graphic Settings <i>NS2: All set to high, only infestation is set to low.</i>

<b>Computer 2:</b>
Modeboard: <i>MSI X79A-GD65 (8D), Socket-2011</i>
Memory: <i>Corsair Vengeance DDR3 1600MHz 16GB CL8</i>
Cpu: <i>Intel® Core i7-3930K Processor (4GHZ)</i>
Graphicard: <i>Nvidia GTX 680</i>
Graphic Settings <i>NS2: All set to high, only infestation is set to low.</i>

Both has the same problem since patch 228. The day where the new infestation got released on patch 228 I have a very odd fps bug. I have in outside of combat iabout 80-100 fps, but as soon I enter combat my fps drops to 45-55 fps which is good but it feels like slow motion. Feels like my fps is 10-20fps and not 45-55 fps. Exstremly slow and frustrating.

Is this issue already known? If not , then I'll go deeper and investigate. Please confirm. :D
