Viggen Performance

Maybe the improvement is due to the memory fix implemented by ED?

Hmm.. don’t think so, look at post #42 by Cobra. Looks like a specific Heatblur patch.

The framerate variance fix should be in this one, but I can't confirm at present.

With yesterday patch my fps improved a lot, even the cockpit seems to look a lot better.. good work!

Works like a charm again, thank you! :thumbup:

I have updated to 2.5.1 a few hours ago. I have to prove it a few times more but for me this seemes to work like a charm too.

The frame drop from 60 (vsync'ed down from 90 to 60) to approx 40 when flying near trees is gone ... YESS! :joystick:

EDIT: I finally managed to find out the problem on my machine.

Many trees, Default Terrain Shadows and AntiAliasing together killed my frame rate.

It was not related to anything else I think.

Strange just did a clean installed today and just took the Viggen for a test flight. Radar on I get maybe 5 frames a sec and freezes galore unplayable. No mods running. Vanilla DCS. Never as bad as it is now (for me that is). Prior to the update it was a bit sluggish but nowhere near the slide show I'm experiencing now.

What is your computer's specification?

Using the lowest possible settings of all time I have 28-32 frames on my laptop with 1.5.8., and had 5-7 frames with 2.5.0 (tested it a week ago or so). So it was literally unplayable with 2.5.0. The main problem with my laptop is the graphics card, which is at the lowest possible minimum requirement. And the loading time was approx an century for a simple mission :music_whistling:

But my power machine is able to handle 2.5.0 (and 2.5.1) very well after knowing about the issue with the trees, the terrain shadows and anti aliasing.

Hope you can find out a setting that works better than slideshow.:noexpression:

It would be useful to us all if you could confirm one way or the other!

Super happy these forums are so helpful, I've just played mission 3 in the Red Flag campaign and was encountering some serious frame rate issues - PC spec is decent (4600MHz cpu, 32 gigs of ram, 1080ti & SSD) and it's the first time I've had performance drop off that bad, its good to see that its a known issue and that Heatblur are on the case as I absolutely adore this module - big thanks to Cobra847 and the team who respond so quickly to problems like this.

Considering that my min FPS while taxiing to the runway went from 17FPS to 44FPS, no driver update in between. So if ED has nothing improved on their side regarding the Viggen only i would say the fix is in.

Not everyone is seeing that. There may have been ED improvements. We just need the devs to confirm rather than us all speculating on yes or no!

I only see this FPS improvement with the Viggen, so my guess is it's in. But you are right, an answer would be nice.

Well the memory manager change and anything in 2.5.1 beta affected my load time immensely. Yes there were changes, perhaps not directly to Viggen, but engine optimisations. Those were publicly listed, but unfortunately lack detail on what you might see, since it affects hardware differently.

So not sure if you will ever get the answer you want, but you may have got the result you needed.

Yes my loading times are also better(in all modules), because of the memory manager i guess. But i have a little AG and anti-shipping training mission, i start from the same airfield with different airplanes and only the Viggen had bad performance on my PC and flying low level since DCS 2.5, not before 2.5. After the 2.5.1 OB update it's back to the same performance i get in the other planes, i didn't see any FPS improvement with DCS 2.5.1 in other planes for me, only in the Viggen. Thats why i'm guessing that the fix is in. But without an official answer you are right, it could be an problem in the engine that ED fixed and the HB fix is not implemented yet. Makes no difference in the end for me, because it work's now fine.

Yes, the fix is in. :) I actually confirmed it in the changelog itself, but failed to post here seperately.

Glad to hear it has dramatically improved the issue!

Thanks Cobra, good to have it confirmed.

Any news on the Kneepad issue that features in a few threads?
