Last Update Rendered Game Unplayable in VR

[Tinkickef]

First time ever I have had to say DCS is completely (Edit: partially) unplayable, but after the last update it now is. FPS must be around 4. The extent to this is that looking up at the moon and moving the head makes two moons appear.

Downloaded the update Wednesday and first time I tried it is today, PC switched completely off between times.

 

Windows update is disabled, so the problem is not one of their updates.

Try deleting the fxo, metashaders, and metashaders2 directories from your /users/username/saved games/dcs.openbeta directory.

thanks for the quick advice Fee. I will give it a go. That's when the nausea goes away :cry:

No Dice, still unplayable. Log enclosed. Tried deleting metashader2 folder again and running repair option, still the same. Shutting down in task manager, I noticed the game is using TWICE the RAM it normally does. Normally when game is idling and I shut down in task manager I see around 4GB RAM used. This time it was over 9GB.

Sorry, I don't use VR so that's all I've got. If you need to revert to a previous version you can find a guide HERE

Done some more testing. Problem is confined to Persian Gulf map. NTTR, Normandy and Caucasus work fine.

 

However if you try PG first and get jitters, then back out onto one of the other maps, you get the jitters on them all.

If you close back to desktop, then restart DCS, everything is fine.

 

Happy days. Give the devs something to chew on.

 

I will rethink my previous observation: DCS is partially unplayable. :)

same problem in vr, fix for me was go to f10 map zoom all the way in and all the way out let it fully load when doing so. No more stutters and low fps...

I'll try that as well: fps has been quite horrible with Update 4 and 5 in VR indeed.

Thanks Sniper. Tried it, no dice. Problem still confined to PG map.

Someone on Hoggit mentioned taking off the headset for 20 seconds or so, then putting it back on.

Tried it and it works.... for awhile, then it starts again.

 

Got the Hornet started (PG, night mission, clouds and moonlight, cold and dark start), turned the flashlight off and the stutters did not return for a significantly longer time than previously, maybe 3 minutes as opposed to 1 minute.

 

Took off and jitters did not return at all once I flew out of the clouds.

I had this issue I tracked it to the latest Nvidia drivers not working right, completely uninstalled them and then reinstalled the latest ones fresh and it worked

 

also reverting did work as well.

I had the same idea: I completely removed the driver in Safe Mode, re-installed it and it did indeed improve performance, but still not up to the point it used to be.

I'll have to do more testing, but it seems to work for me as well. Thank you!

 

If this indeed turns out to be the work-around, it could indicate the new memory manager (perhaps Update 4 and 5 contain "optimisations" for said manager?) is to blame for the recent performance drop...
