Issue, when the game starts my fps is a stable 60, then when the game progresses it gets worse and worse. Now this is nothing new at all for Sins of Solar Empire, even though it gets really annoying if you got a 5 hour 44 mins game and of that 5 hours you play with 20 fps. 

Now what I noticed that might not help at all is my GPU Clocks. Which might add to the games lag.

Sadly copy paste the log file doesnt make it look readable so in a nutshell, it goes from no gpu activity to 4% to 0% to 4% constantly resulting in my clock speeds doing the same thing. This is happening during a new game or 5 hours into it with massive battles, the graph is looking like /\/\/\/\/\/\ that. 

I tested Skyrim, Neverwinter, Planetside 2 and they all remain at max clock speeds. I tested modded, unmodded, modded exe file and unmodded exe file but the results are the same. any clues?
