Getting extra VR performance with my current rig

[westr]

Hi looking for some advice. Specifically from anyone who has a similar build to my rig using an Oculus.

I put together my current rig about 1yr ago. I use an Oculus CV1. I enjoy mainly 45fps in all the modules I own in most circumstances, and I am able to have nice detail in my settings. MSAA x2 shadows high textures high. Pixel density 1.6

I have spent hours perfecting my settings to the point where if I lower any individual Items in settings from this point it makes very little difference to my performance I’ve also spent a long time playing with pixel density to get the best performance/look so I’m happy where I am with that.

Some modules work better than others the F18 I find runs better than any. Some others not so well. The Spitfire on the Normandy map runs worse than any other. However this has improved since the latest OB updates and generally I can maintain 45fps.

Where I seem to suffer and it certainly prevents me from purchasing any of the campaigns put together by 3rd party developers is when I have large volumes of ai aircraft. Ground vehicles don’t cause as much of a problem but It still has an effect. Missions on the Caucasus with the hornet I can add decent levels of ai aircraft. But say for example I have a flight of mustangs or spitfires in Normandy and I’m flying in close formation I then get involved in a dogfight with a large number of 109s. Then I really notice a large drop in performance. Sometimes down to 12fps and it’s just unplayable. Or also say a large formation of B17s this has a big effect on performance.

So at this moment in time I have a Ryzen 7 2700x CPU. I have all my memory slots filled with 32gb of Ram

and a GTX 1080ti. I can’t see any more advantage gained from RAM or would someone with VR experience disagree? Is there a single change I can make that will help with high object count in missions. CPU, graphics card, someone even mentioned on the forums they noticed a performance help from going to a HP reverb, or is it simply one of the disadvantages of VR?. I don’t really want to construct a whole new rig only having this one for a year. I look forward to any advice from VR users. Many Thanks.

Edit: I also have DCS world installed on an NvME SSD so cant really improve on that either.

Helped me a bunch to squeeze every ounce of performance out of my rig.

Hi - big performance drop when encountering large aircraft formation is due to "turbulence wakes" option (computation impact of many turbulence wakes crossing each others).

Prefer to disable this option when playing this kind of scenario.

You're CPU limited. Which is OK, we all are. Note, some of your graphics settings put as much load on the CPU as the GPU, shadows being a good example

 

Eventually you will probably want to drop a Gen3 Ryzen in there, it makes a big difference. In the meanwhile, when you're on a busy map, reduce shadows and vis range.

 

If you upgrade to a higher res headset, only thing you'll change is anti-aliasing settings. More physical pixels you're driving, the less anti-aliasing you'll need. Won't affect the behavior you describe one way or the other

Ok some good pointers there to look through. Thanks everyone, I hadn’t even considered wake effect having a performance impact. Interesting.
