DCS 2.9 and Intel Extreme Tuning Utility = Stutters and Crashes

[WipeUout]

I have been experiencing major stutters and the sim crashing as soon as I would try to engage DLSS / DLAA / TAA after a few seconds.

I tried various combination of PimaxXR/Pimax Client / Quad views on/off etc...  Sometimes, the stutters would go away butg after a few minutes woudl intesify.

Until I started to stop all overclocking and found out that the Intel Extreme Tuning Utility was the culprit.  It was set to automatic OC and it does not play well with DCS 2.9.  I have not checked if the OC is set to specific values it would work, but for sure when in auto OC, it does not.

Now I am experiencing the most fluid and smooth siming ever.  DLSS is a bit blurry but so much smooth that it is worth the compromize for me.

I’m running an overclocked 13900K @ 6.2GHz without trouble using 2.9. This is with the Asus AI overclock from the MB and not the Intel utility. Perhaps the Intel utility is simply applying too much oc.

Personally, I don't see the point of overclocking the 13900. It runs hot as it is so overclocking you are very likely to hit thermal throttling and may end up with the CPU running at slower clock speeds than if you were running at stock settings.

This is way off topic, but the best way to OC a 13900K is to use adaptive voltage and loadline calibration to create the headroom to do a larger overclock on a smaller number of cores rather than overclocking all of the cores at once.  in other words if you are only using 4 cores then maybe your overclock is 6ghz, but if you are using 6 cores your oc is 5.8, and 8 cores it's 5.6... this avoids the thermal problem with the 13900K you mention if done properly. (of course maybe you knew all of this already)  if you really want to dive deep, this is the resource...  This guide was written for ASUS motherboards, but the concepts apply  to any motherboard with the 13900k.  Mine does not run hot at all in this configuration.

With a decent cooling solution it’s basically a free performance boost for the effort of clicking a button on the motherboard utility. That being said the 13900 has a normal boost clock on 5.8, so 6.2 is exactly the benefit it sounds like. But it’s free, so…
