Ok, so we all know the common stuttering problem on PUBG.

Well after switching from a Core I5 to a Xeon on my main platform, I got stuttering issues and fps drops for some unknown reason, so I got interested and started to investigate.

Now I know, and many of you as well, know how bad a game can be optimized (looking at you, Ubisoft). But what if I tell you PUBG has a flaw in it's programing which I found out yesterday?

I'm talking about HyperThreading.

See, when I had the Core I5, I only had 4 logical cores, which as we all know 1 core does 1 thread.

Now the Xeon X3470 I got has 4 logical cores and 1 core does 2 threads, so it has 8 virtual cores.

So if PUBG needs for ex. 4 threads handled to run the game OK, on the I5 it will use all 4 cores, but on the Xeon with HT it will only use 2 cores x 2 threads = 4 cores, hampering performance and stuttering and fps drops will occur,

Now I immediately worked out a solution to this problem I had, and many of you possibly have:

Task Manager > Processes Tab > TslGame (right click on it) > Set Affinity > Mark Cores 0, 1, 2, 3 only.

Apply and continue playing the game as it is.

This is not a problem on the newer I7s and Xeons, as much as on the older ones with lower single core performance.

Let me know, guys what do you think of this, and has anyone ever had similar problem?

Have you tried using the launch option -USEALLAVAILABLECORES turn off full screen optimization/gamemode and make sure its running in true fullscreen not windowed full
what kind of frames are you getting?

I'm not having issues and I played on my 2600k and now my 8700k. both have hyperthreading. or maybe i have alot of true cores to begin with?

maybe the problem is in your 8GB/HDD installation(if pubg is not on the SSD yet). i had stuttering problems on my laptop because it has a 8GB and went away once I installed PUBG on the SSD

meanwhile on another desktop on our house there's no stuttering with 16GB Ram even though i had it installed in an HDD

No, the I5 ran PUBG on 8 or 16GB ram same, and no difference if it is on SSD or HDD, tried that, didnt work.

Game runs on 1080p True Fullscreen mode with high setings with Vsync and Motion Blur off.
