I experience random short stuttering each 30-90 seconds. It happens in each map. I also tried no mod test, only performance mod test - still the same.
My graphics setting are on medium. Tried lowest and highest ones - no luck.
This also happened to me with previous STP versions like 3.8 and some others.
