Thanks, will probably update to dual-channel as soon as possible, but as i said, don't think thats the reason of the stuttering.
I can post some gameplays, but i've never recorded and i don't have that much experience on it. Any tips on programs just to record gameplay?
Edit: Can you see the little stutter on 4:48 left side of the screen in the video you sent me? thats exacly what happens to me, more frequently on PUBG than other games (on RE 2 remake for example, i rarely ever encounter one, with say, 1 stutter for a minute), but for PUBG would be like 1 stutter each 5 seconds.
I notice in the video that the left side (single channel) tends to stutter a little bit more, but that i could be wrong, i will try to update it to see if helps or fixes it.
