counter25 Posted March 16, 2022 Share Posted March 16, 2022 (edited) 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 https://www.userbenchmark.com/UserRun/51189246 Edit: I found that the issue is especially noticeable when flyiing the MI-24P. I also attached a screenshot of my task manager: Edited March 16, 2022 by counter25 Link to comment Share on other sites More sharing options...
Flappie Posted March 16, 2022 Share Posted March 16, 2022 Try this: Go to "Saved Games/DCS.../Scripts/". Rename your "Export.lua" file so the game cannot find it. Run DCS and see if that changes anything. If you have no Export.lua file, disregard this solution. 1 Don't accept indie game testing requests from friends in Discord. Ever.

counter25 Posted March 16, 2022 Author Share Posted March 16, 2022 Thank you for your hint. Unfortunately renaming my export.lua did not change anything. Link to comment Share on other sites More sharing options...
EL CARIBE Posted March 16, 2022 Share Posted March 16, 2022 I understood DCS does not support multi-core at present. Could that be the issue? Link to comment Share on other sites More sharing options...

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... Link to comment Share on other sites More sharing options...
Zeagle Posted March 16, 2022 Share Posted March 16, 2022 Which motherboard? Also I don't know how well the 3070 does at VR. Link to comment Share on other sites More sharing options...

Motherboard is B450 Tomahawk Max; As I wrote above it seems that I am bottlenecked by the CPU as the GPU still has headroom. Link to comment Share on other sites More sharing options...

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.

fab.13 Posted March 16, 2022 Share Posted March 16, 2022 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.
