Hello people.

I have a quite bad experience in VR with DCS.

(On a screen, it runs smooth on high/ultra settings).

My specs: Ryzen 5700X3D, DCS on a M2 disk, 3070 rtx, 64 Gb ram.

I use oculus tray tool, debug tool, .... But i think my config is simply too short. 

I think this can be due to 8Gb VRAM. Do u think it can be useful to switch to a Radeon 7800XT for example ?

Looking for that one, quite cheap.

VRAM matters in DCS-VR. I switched from a 3070ti to a 4070ti super - so from 8gb to 16gb ram and the impact was huge.

i9-9900K / Bios Profile XMP2 / Rog Strix Z-390F Gaming / ASUS TUF Geforce RTX 4070Ti Super / 32GB HyperX Fury 2666 / Saitek X52 HOTAS / Pico 4

Are you using Meta link?  If so, it is known to struggle with lower VRAM.  I would recommend trying Virtual Desktop, although you do require a Wifi6 compatible router and ethernet cable to your PC, its a cheaper option.  I can confirm it was a game changer for me and others have reported the same thing, mainly due to the codecs and streamlined software approach instead of the notoriously bad Meta software.

Also has the additional bonus of only having increased gains if you do upgrade hardware in the future.  I've recently upgraded and am able to push the resolution high enough through VD and headset, that i no longer require any form of anti aliasing.

You wouldn't think it makes sense you can get better performance through streaming than a wired connection, but it really is the case, especially if dealing with low VRAM.

Thanks for your answers.

I've bought Virtual Desktop, but (after a short try on DCS) it is stuttering. 

Looking now for some advice, setting up Virtual Desktop.

I use hvec-10 codec at 200mb 100% sharpening at 72hz or 90 with asw on using ultra mode

 

the av1 codec is broken above 120mb

 above 120 it crashes after a few minutes so I switched to hvec-10

Definitely VRAM.

For VR, 16GB is minimum IMO. If you are looking at 7800 XT, I would wait until the 9070 XT pricing is announced (supposedly) next month. You could also see if you can find a good used RTX 3090, 4080 Super, or 9700 XTX. VR should get a reasonable performance bump once Vulkan and DLSS4 (at least for Nvidia users) is released.
