Effect of hardware virtualization on cpu usage

[skypickle]

With msfs 2020, turning off hardware virtualization in bios improves performance.

however, I don’t see much improvement in dcs.

z490

32 g ram ddr4 3600

 

does anyone else see this? Perhaps I need to ‘optimize stuff’

This is a "red herring", and it has nothing to do with the DCS engine.  Your GPU is designed to run at 100%, but with the CPU, after 50% performance starts to degrade.  After 85% you are hitting max CPU utilization.  The idea that if my CPU was only running at 100% I would have better FPS is just wrong.  There are lots of threads here on how to tune DCS settings.  Perhaps you should be more specific about what you are trying to achieve.  Happy to help out.

Don’t really know where to begin. Running Msi afterburner I can see cpu and gpu utilization- neither goes to 100% even when I am seeing 30 fps in multiplayer servers. Running an overclocked 3090

DCS does not get anywhere near 50% CPU utilization unless you're using a dual core CPU. Core utilization is what matters, since all of DCS except the sound system runs on a single core. When people report low CPU utilization, it's typically one core pegged at max and the others idling, because that one core is where DCS is cramming everything. ED is working on a major overhaul that will enable it to use multiple cores, but it's still some time away.

30 fps is perfectly acceptable so long as it never drops lower.  I've never played multiplayer, so I can't speak to it.  Speed of Heat's VR settings are a good place to start.  These are conservative settings that you can increase one by one until you find the sweet spot.  I turn off terrain shadows, set Visibility Range LOW, MSAA x2, resolution 1440p.  SSLR and SSAA are expensive settings to enable.  If you are stuck at 30 you may have Vsync turned on in game settings or the NCP.  I use vsync and get a solid 60 of course in single player with my 3080Ti.  You can post screenshots of your settings here if you like.

DCS 2.7 is not running in only 2 CPU cores now. And it only occurs in DCS 2.5.5 or ealier versions. DCS 2.7 now consumes too much CPU cores that it can cause high CPU temperature...

If your CPU has cooling trouble, upgrade your cooling. If you want to do CPU-intensive stuff like gaming, it should be able to run at 100% for extended periods of time. I have an off the shelf water cooler now, and I'm looking into a custom water loop for my next rig in order to hopefully do some serious OC.

I doubt that DCS is the reason why an adequate cooled modern CPU gets hot.

Ryzen 5000 is somewhere 12-14watt per core under full load, give or take 2-3 watt depending on 6 core or 16 core CPU. 
 

i would check cooling if DCS melts your CPU
