CPU/GPU Usage Spikes

AgentXIII: Been looking at this issue almost all week, sorry for the delay. (JIMSTER305 I'm looking at your ticket right now as well) @helaku, I would love to see your dxdiag and preferences file. I tried to see if you had a support ticket in with us and couldn't find one.   Just my train of thought on this though, it looks jitter on the card. This could be affected by too good of hardware and options like vsync would lower the fps a little but make the frames smoother. What I would love to have you guys try is turning off Areo and theme support in Windows while running WoT. This is easiest on Windows Vista/7 and possible in Windows 8/8.1 but a pain to do as the logon process restarts the dwm process, so you have to disable the windows logon process as well. (not really worth it) Also, I have yet to play with Windows 10.   Right-click on your World of Tanks icon located on your desktop. Select Properties.  Then, check the Compatibility tab. Now, check the boxes to Disable Visual Themes, and Disable Desktop composition. Select Apply and then OK.   This may not fix the issue, but it's helped me with many games on my home machine so its worth a shot. (especially if you are running 2 monitors and have video or flash on your 2nd screen while playing)   If you guys send in tickets, please be aware that my response times may take longer than normal, but rest assured that I like to look at every minor detail, from PSU voltages, clock speeds, running processes, I could go on, but this means I may end up asking for GPU-Z logs or Aida reports <-- I love event logs here, sometimes you can see issues from other games that resolve the issue for WoT.   /endrant, I'm going to get back to the ticket submitted by JIMSTER305, but if anyone else is also experiencing a similar issue, please send a ticket to Customer Support.
