Hi all,

Recently I have noticed some weird behavior while gaming, especially for battlefield (1,4 and V).

CPU11 ( CPU 10 in task manager) is always pegged at 100% and causes sever stuttering in BF1 and V. BF4 is not affected by this behavior.

And if I set CPU affinity by unchecking CPU10 in task manager, the game become silky smooth.

The only other program running along side the game is MSI Afterburner, but even if I close it the stuttering does not go away. Only setting CPU affinity solves the issue.

Any ideas?
