bottleneck?

[C6_Geo]

Hi guys, 

I got an I5 6600k with (OC genie to 4.1) and a RTX 2070 with 16Go RAM

in VR i got 32 to 90 fps but for exemple on berlogat with 25 pilots it's 43/45 fps max.….

I d'ont understand the problem.

Some CPU/GPU monitoring to show you if you see Something. Thanks  a lot!

(Sorry for my bad english^^ )

 

Nb: i'm a noob with CPU/GPU analysis... but it's seems to be a CPU limited state?

Your cpu is running too slow and the 2070 isn't that fast.

CPU is bottleneck. 30% GPU usage tells it. What helped me alot I changed steamvr to opencomposite open vr software. Steamvr background CPU usage was something like 45-55% ! Now it's ~25% . Worth to try. At least it helped for me

Edit: With i5 7600k 4.8Ghz gave me most fps but to get it stable I lowered it to 4.6Ghz. now I can see nice 70-95% GPU usage 90fps and 50-80% CPU usage

 Thanks for the tip Hartigan it seems to be far better!

do you think that overclocking my CPU manually will be a good solution?

Well it depends what motherboard you have ,but this first post from Google should be helpful . It seems to be step by step and those settings should apply with many different motherboards.

If you are unfamiliar with BIOS it's good time to start and first you can skip memory (dram) overclock. 

Btw many mobos have XMP dram profile in bios. My dram is 3000mhz but it run only 2133mhz by default unless I set it work with full speed by applying XMP profile 2. from bios. It's easy to do and  that is important for VR performance

Same happens with my 8700k 5.1 and 1080ti OC.

Dude you don't have to prove anything to me, I have the same setup.

[E69_Qpassa_VR]

Yes I know, I have seen your signature?. It's to add more screenshots to the topic

[E69_Qpassa_VR]

This still happens and it's not because the CPU cores are at 100% load... any of you guys experiment the same?

They are at much more than 100% load. They just shuffle the thread around so it looks like less. That's why they look like this. 

 

You must use fpsVR and watch CPU frametimes.

 

Windows task manager or other monitoring programs (cpu-id) are often used, but easily misinterpreted.

Mmm I have bought the fpsvr, and because of this I have seen I was using 200% instead of 150%, it seems the configuration on SteamVR is quite buggy when you define the Super sampling.

Could also be auto-throttling the VR element, so if it cannot get 90 it drops to ensure 44/45 at 50%.  What headset?
