Performance in VR. Are they testing?

[Tweety777]

My experience with Kola on my Quest 2 powered by a 7900XTX gives me fine results at very high graphics settings, and I might add that it is stunningly beautiful to fly through though there is room for improvement outside the well detailed areas. Only problem I have is that flying my wingtip almost into the mountain at like 500knots feels almost like driving past it at say 100 knots.

In terms of performance, I must start by saying that my current motherboard is not capable of fast enough USB speeds so my GPU and CPU usually run at about 50%, then I get between 36 and 72 FPS, the latter being the refreshrate of my Quest 2 during testing.

I find it odd we get so many very different opinions on how the map runs on people's system in VR.
I had another go at it yesterday: empty map with 1 flyable aircraft and some weather, and I get 16fps down low - I have to climb above Angels 15 to get framerates that don't make me throw up.
With the very same DCS settings I get 40+ fps down low on other maps

I have this weird problem where it performs okay (35-50fps on the ground in Rovaniemi) when I don't use the F10 Map but as soon as I use the F10 map a few times performance plummets to something like 15-25fps on the ground around Rovaniemi or the Finnish road base. Other locations like Bodø still run absolutely fine, mostly around 50-60fps in VR. Only after restarting DCS will performance be back to playable levels.

Yeah I think its a vram issue. If I use a lot F10 -> F1  -> F10 -> F1 my vram is overloaded and stutter begins. Thats why I always keep the Task manager in the background and Alt+tab Task Manager -> back to DCS which seems to "reset" vram. Bug?

For me this doesn't always work. I recently did a ~1000 nautical mile flight around the map in the Viper: Bodø - Kiruna - North Cape - refueling over Kirkenes - Murmansk - Olenogorsk - Kola NPP - Rovaniemi and I was stuck at around 17fps after I landed, no matter what. I tried tabbing out, closed all other apps except for Task Manager and WMR - no dice.

I do exactly the same. And I see it real time, on the OpenXR Toolkit overlay VRAM usage, going from 100% back to 60/70% after you alt+tab. We have reported this, they don't care.

Do not care about what ? the performance in VR with the kola map ?

As always, the process of defining issues, finding them, and ultimately solving, is a lengthy one. That is particularly true, in the event where some get it, whilst others don't. Statements in the sense of "they don't care", are literally made by kids who haven't learned the word "patience" yet. If "they didn't care", DCS would not be where it is today! That is particularly true with us who have been here for 20+ years!
 

The process of bringing DCS to modern standards, is a lengthy one. There is no easy way of acquisition. Then there is the question of priorities. Lastly, Kola being a new map - it will take time for it to mature! Besides pressing issues, the next update is expected around June. Until then, if performance suffers, simply lower your settings. It's that simple! (Consider how much more demanding Marianas is to e.g. Caucasus. Marianas, barely has any land, compared to Kola.)

This is not something that is not specific to the Kola map. It appears to affect some people and not others. It has been discussed at length in other threads. I have a 4070 with 12gb VRAM and I do not experience this issue with the Kola map. 

I think that low fps down low is simply an issue of trees and ground assets not being optimized yet. Above about 2000 ft I get a steady 72 fps.

I have a 7900XT(not VR, 1440p monitor). I think Kola is very poorly optimised at this stage. In the Rovaniemi Airport I get a large fps drop if I look a certain way. I don't have any problems with other maps. They seem to have optimised the trees, but I don't understand what causes this fps drop - maybe rendering distance, maybe something else.

Great map, but performance needs to be globally overhauled.

Any possible performance improvement after the recent patch?

[Kiwi_Viper]

no its terrible, compared to all the other maps Kola is by far the worst even with a high end system and upscaling in the crystal 25-30 fps is really bad, every other map im getting 70+ maybe the upcoming new textures will help as it is now its unusable

I have no problems with Kola, Afghanistan is much worse. Flying the F4 on Kola is smooth and nice.

yeh but do you  fly only VR i do, in 2d there all 120fps+ but VR is very hard on gear lol it is a little better now im back on a 4080 but not great, amd cards are hopeless for vr they dont so foveated rendering at all, after using orbx scenery in msfs i expected better but it aint finished yet so time will tell

Yes, I only fly VR.

I just bought the kola map a few days ago. I don't see any performance problems playing on multiplayer servers. Everything runs fine and smooth and I really like the map - didn't expect that.

The only thing I am missing are more airfields and maybe some summer textures, but I heared it will probably come with the next update package.

 

Hardware: i9-14900k, 48 GB RAM, RTX 4090, HP Reverb G2

Settings: DLSS, Quality and highest settings (textures, sharpening, clouds, view, water...)

The Kola Map is by far the worst Map if it's about FPS!

I can play all other maps with 72 FPS at ground, and here and there a few short FPS drops lower than 72. But the Kola Map gives me steady 60 FPS low flying and on the ground 50-40 FPS at the lower end.

I will stop playing this Map, after I have finished the F16 Campaign. I thought about buying the F18 Campaign for the Kola Map too, but no, that would be a pita.

The funny part is, the Buildings' or models of other Planes or Helis are not the FPS eaters, and it doesn't matter how many of them I can see. It's all about the trees!

So, RIP Kola for me and >>any<< Campaign or server with this Map!
