CPU Cores at 100 percent

[counter25]

Hi!

Recently I noticed that my CPU usage when playing DCS online (VR) is 100% on two cores all the time, while my GPU usage is only around 80%.

Does anyone have an idea what I can do to reduce this bottleneck? Would it help to reduce the preload radius (currently at 35k)?

Thank you!

 

Specs:

Ryzen 5600X, RTX 3070, DCS on dedicated SSD, 32GB Ram @ 3466 MHz

Edit:

I found that the issue is especially noticeable when flyiing the MI-24P. I also attached a screenshot of my task manager:

Try this:

1. Go to "Saved Games/DCS.../Scripts/".
2. Rename your "Export.lua" file so the game cannot find it.
3. Run DCS and see if that changes anything.

If you have no Export.lua file, disregard this solution.

Thank you for your hint. Unfortunately renaming my export.lua did not change anything.

I understood DCS does not support multi-core at present.   Could that be the issue?

It is true, however, the CPU I chose is rather strong in the single thread regime, which is why I am surprised that it is bottlenecking...

Which motherboard?  Also I don't know how well the 3070 does at VR.

Motherboard is B450 Tomahawk Max;

As I wrote above it seems that I am bottlenecked by the CPU as the GPU still has headroom.

Normal behavior online for me as well

Thanks! At least I am not alone. I hope that this will improve soon ...

My testing revealed that I got quite a bit of performance boost from disabling shadows. It is not pretty but better than a slideshow.

Hello,

In VR the goal is to balance Frequency vs Quality
If you get a High Frequency with Quality for your eyes, then you have no problem.

This is my opinion about this subject

 

Then after, you cloud use a tool to get CPU frametime and GPU Frametime while playing
It will be more accurate than basic Windows monitoring to find where to optimize or reduce load.
