DPCs and ISRs are fine:
Elapsed Time, > 128 usecs AND <= 256 usecs, 5, or 0.00%
and your AMD Radeon HD 6970 is bored with a resolution of 1280*720 (Why not use 1980*1080? Your Dell ST2220M supports FullHD and the GPU is fast enough). Deus Ex - Human Revolution uses 1 core heavily. But I can see that the Audio service causes 7s spikes (AudioEng.Dll!CAudioProcessor::ProcessEachAPO which calls the audio drivers - MBTHX64.dll/Creative Audio Processing Object Module) every 6s. So try other audio settings in Deus Ex (no EAX and other things) The Realtek High Definition Audio is a cheap chip which is ok, but not the best.
Thanks for checking the log.
I play most games on my TV, which only supports 720p or 1080i (and it's a CRT so can't properly resolve even 720p I don't think, plus there's the flicker with 1080i).
I'll try tweaking the audio settings. It seems to be OK after rebooting, but does stutter a bit from time to time (although that may just be as it's loading data) so perhaps I can get it smoother with different settings.
EDIT: Seems there's no audio settings in Deux Ex (other than volumes) so I can't do much there. There is a separate THX TruStudio Pro driver for this motherboard, which just gives effects which I don't want, so I haven't got that installed at the moment as then I have to disable all the effects, prevent it loading at startup, etc. Maybe I'll grab a trace with another game and you can check if that shows the same issue with the Audio service.
