My Setup no issues

[Bandit47th]

My Rig

I7 8700k OC to 5GHZ

32 GIG Ram

3070 RTX

2 M.2 drives

32 inch Dell Monitor 165 HZ

I have set my Monitor to MPRT 

Settings in game are; Textures Medium Terrain Low Clouds Standard DLSS Balanced Visibility Medium .

I found high settings in DCS uses almost all of my 8 GIG of video memory while medium uses 4 GIG.

CPU is at 49% ram is at 20 to 28 GIG depending on mission.  With these settings I have no micro studder or lag spikes . 

While DCS has a recommended  system set up listed , at least for me, it seems you need 16 GIG or better Video Card and plenty of RAM 

to run all at max settings .

I´m not sure if it is an issue if DCS uses all RAM or VRAM available. I have the components mentioned in my signature and even the 16 GB of the 4080 are maxed out without having issues with stuttering. Based on my experience DCS tends to take what it gets, especially the VRAM.

The 49% of CPU usage is not very specific. The 8700K has 6 cores and it could be that 3 cores have a load of 100% and the rest 0% which gives an average of 50%. This can also been spread over more cores with less load coming to the same result. I guess you know what I mean.

64 GB of RAM are a good thing on busy servers on RAM demanding maps like Syria. In single player 32 GB should still be OK.

Running max. settings is not a matter of the amount of RAM or VRAM only. A slow card with a lot of VRAM does not necessarily end up in the possibility to run max settings.

A good rule of thumb is if the GPU has a load of 100%, the CPU is the bottleneck. If is running with lower load, the GPU is the bottleneck. Watching the usage of RAM and VRAM and also the GPU/CPU usage gives you a good indication on where you stand. Playing around with the settings in DCS can give you a good and playable state like yours.

Conclusion: It is always worth to spend time into playing around with settings etc. to get the best out of DCS. Even with my system I did not max out everything completely. Be careful, this can make you addicted in updating your hardware. I know what I´m talking about

This is not an exaggeration.
