I know this is a few months old, but I also experience this. Hardware in signature.
I also get this when using LinX. So, from what I understand, a 'proper' stresstest will consume 100% of the CPU, meaning some lag is normal.
I also experience this in:
- IntelBurnTest (very minor and hardly noticeable)
- x264 FHD Benchmark
- LinX
x264 FHD Benchmark and LinX have similar threads with different hardware - the general consensus is that it's down to the way the software stresses the CPU - it's supposedly a good sign that the maximum amount of usage is being utilized.
I don't get this when using:
- Cinebench
- AIDA64 Stresstest
