FPS drop after F10 map

[Reflected]

I mean what on earth is this? Mother of all memory leaks...

After using the F10 map - Alt Tab out of DCS ("Window out of focus" message appears), then Alt Tab into DCS again and Video memory will be restored.

Thanks we’re all aware of this workaround, the point of this thread is that it shpuld happen twice per mission in the first place.

Since the latest updated (2.9.6), this issue still persists.  One user has suggested using Alt Tab to restore the video memory, but this does not fix the issue for me. Is it possible to get an official update on this game breaking bug yet?

This issue needs more prioritisation now that the 'dynamic spawning' essentially loads into the F10 map first, forcing VR players are into this situation.

Just came here to see if this was already reported or if it's just an issue on my side.

"Happy" to see I'm not the only one

 

Hopefully it gets solved soon.

 

Thanks for sharing the temporary "alt-tab" work around! Saved me having to force-quit an MP session a couple of times today

I tried to enter the "enigma cold war" server several times without success, because when it loads the map my PC crashes. I think the update made this situation worse. THE The fact of starting immediately with the map open is not great...I also notice that my 32GB of RAM is being totally drained, with 99% usage. I ordered new RAM to reach 64GB, I hope it solves the problem. At the moment Alt-Tab doesn't work for me either.

I have yet to experience this problem prior to the 7/11 update. However now it's a tremendous issue for me... how does one alt tab out of vr? I have to use my quest 3 controllers to get into menu mode with desktop view enabled to view my desktop. My keyboard doesn't recognize like that while in VR.

An easier solution for Quest headsets is to send the headset to sleep for 30 seconds or so. Wake it and it should have flushed it like you alt-tabbed.

can try that, hold a stable hover in vr lol

Yeah it's not ideal but I got into the habit of having to do it when I first started playing 3 years ago on my 3070.

Eventually I moved to a 3090 and the problem goes away as it's vram related.

You can take some steps to reduce how often it occurs (installing the blank hanger mod, locking F10 to aircraft position and having it fairly zoomed in) but due to the recent changes in the slotting system, the game forcing F10 open immediately on load-in is probably making the situation far worse.

As an example, my vram usage (not allocation) hits over 14 gigs just to get to the slot selection screen on ECW. Now after taking a slot, eventually that vram releases to under 8 gigs. But anyone with only 8 gigs is at risk of a vram overload (and then this related problem) pretty much straight away.

Oh, if you can get any tracks/logs showing the problem in action please send them my way.

I'm gonna look into the blank hanger mod you mentioned. I have a 4090 and never had a problem before. Haven't played in a few days but when I tried it the day after the update, f10 map came up, fine and all, when I switched back to f1 view I thought my game crashed it locked up so hard for was breaking up for like a minute. Never had that happen ever. Everytime I touched f10 boom same thing on return. I'll give it a shot again.

Mmm, if it's started happening on 4090's that's a bad sign. Previously it was mostly vram overflow issues.

Might be a new problem rolled into the old. Let me know if the mod helps any, though if it's not vram related it probably won't. Still a good thing to have installed regardless imo.

Someone recently released that moving map mod that uses openkneeboard to display an alternative F10 map. That's also worth pursuing, though I believe it is missing features like placing markers etc.

One other option: Try VD instead of link. VD seems to suffer less from F10 transition problems, I always assumed that was all down to vram overhead but perhaps there's more to it.

Empty VR hangar for less VRAM usage and faster F-10 ingame map (digitalcombatsimulator.com) downloaded this, gonna try tonight. VD still confuses me, I use link cable as it charges my Quest 3, I don't want to go wireless, my understanding is VD is for wireless no using link cable? I don't think I can benefit from this. 

[Panzerlang]

FWIW, my 4090 has 24gb of VRAM. Before the update I frequently had lock-ups using the F10 map. After the update it happened on the first use but not since then.

In other news, using Sandboxman's alternate quadview DLL my stutters (looking sideways at low level) totally went away, motion in all aspects is 100% smooth.

My conclusion? DCS is a messed-up bag of spanners and what does something for one user will do nothing for another or will even make things worse. It's headless-chicken code imo.

VD is wireless yeah, runs the data through your router.

You can still keep it charging while playing (it's less likely to lose charge like it can on link, as you can just go straight into the mains) if that's the main concern.

Getting the ideal wireless setup can take some work, but honestly it's worth it. Even if only as a backup option for when link breaks. As an example, OpenXRtoolkit may stop working for link altogether soon (already the case on the PTC).

The sideways terrain stutter is very odd. I mostly managed to fix it by locking the fps via nvidia control panel, rtss and then a combo of vsync fast low latency ultra. It's worked as a fix for some people, but for others it had no effect.

The "fix" also changed the in-game FPS graph behavior, when I was hitting 72fps at 72hz it would previously say I was CPU render thread bound. After applying the fix it now says GPU bound. No idea why.

Thats what I thought about VD, I have a very powerful wireless setup, I have no interest in wireless, I always enjoy everything hardwired. 

Otherwise I tried the blank hanger, it creates many extremely jagged black lines stuttering all over the bottom of my screen now, I am not a fan but I am sure it helps. Tried without it again, F10 map isn't creating issues anymore, it seems this was server specific at the time of my first online play after the update. Still gonna try the blank hanger as I am sure it only help, but those black jagged stutter effects are annoying lol 

Thanks for your replies.

Just to clarify, is this with VD?

Any solution about MAP spwn when entry in the server MP?

[winghunter]

FYI, I've created a F10 map alternative, download here for free. Go to the channel #moving-map-beta

It runs in VR or 2D, or on a second screen like laptop / tablet / phone

Yes, disable/delete super carrier module. Could also try disabling others as well but I don't think that makes a difference currently.

Only time I've seen the frametime a bit like that was the map drawing degradation problem. I think it's been fixed but haven't double checked:

You can/could workaround it by hitting escape while on F10 before returning to F1. Hitting escape hides the map drawing which is/was the source of some degradation loop. The longer F10 was left open the bigger the degradation before it hit a reset point.

It's really frustrating how they ruined a game with the update. It was much better before....It's impossible to play with VR, even turning down the smallest details and disabling everything! I think I'll abandon DCS because it sucks

I would like to know the genius who thought that starting multiplayer with the map is better....

This looks to be real friggin awesome!  What perf impact does it have?  Am I gonna lose some frames using it?
