Can you roll back to Caucasus before the update? Unplayable in VR...

[dmatt76]

The Caucasus map was the only good map to fly in VR for me - butter smooth performance!

Now, after the update it is unplayable, stuttering and slideshhow mostly above buildings and trees flickering different shades of green constantly, possibly shadow problem...
Could have done some backup version...

Now I'm stuck with orange Nevada...

Have you tried to clear the fxo and metashaders2 folders?

[dmatt76]

No, I will try, but I have never had to do it before...

In fairness, since you appear to mainly fly on the Caucus map and it hasn't been updated in a lot of years, that isn't that surprising.  With newer maps that receive regular updates/changes deleting metashader and fxo is 1st troubleshooting step for this type of issue.  When the map you were using hasn't changed, this likely isn't required.

I noticed this in 2d looking into forest at close range.

Framerate got choppy without any obvious update or difference in trees to my eyes.

I fly many different maps, I have deleted fxo/meta every now and then, but I've never noticed any difference with old fxo/meta and after deleting. However, I've noticed for the first time frame drop on Caucasus to the point, that Syria runs much better in VR, without any tree flickering

The map has been updated so obviously there can be some performance difference. Either adjust your settings and move on or be specific if you think there's some problem. Save a short track with Su-25T where you find the most performance hit and upload here.

Edit: DCS updates are optional, so yes, you can roll back for SP.

You can't just roll back a single map or module. You can move to previous DCS version, leaving out any modules and changes that came later.
