Recluse Posted May 30, 2023 Share Posted May 30, 2023 Interesting!!! I have used the ALT-TAB trick in the past for FPS decreases, but it never seemed to work for me with the F10 issue. Not sure how long I held it for, but usually, I would wait until I observed the FPS coming back and then switch back to DCS. FOR ME, the F10 issue totally disappeared when MSAA was turned off (though that is not everyone's experience). Link to comment Share on other sites More sharing options...
chichowalker Posted May 31, 2023 Share Posted May 31, 2023 MSAA off is not an option. Only solution here is that ED fix the problem. 1 Link to comment Share on other sites More sharing options...

Magic Zach Posted June 10, 2023 Author Share Posted June 10, 2023 Alt+tab doesn't fix the issue, neither does putting the headset to sleep and rewaking it. Like said above, only fix is for ED to fix it.

_Mals_ Posted June 12, 2023 Share Posted June 12, 2023 Got the same issue. But it seems to happen only in the F-14 for me. At first it was only in the Levant MP server but since the last update it seems to happen in SP too (I have a rift S, 3070ti, i5-9600k) I'll post a Track tomorrow Link to comment Share on other sites More sharing options...
RealDCSpilot Posted June 12, 2023 Share Posted June 12, 2023 Maybe it's the old VRAM overflow issue. People with more than 8GB won't be able to replicate this. You guys could monitor your VRAM usage and check what is going on when your are switching between cockpit and F10 map. i9 13900K @5.5GHz, Z790 Gigabyte Aorus Master, RTX4090 Waterforce, 64 GB DDR5 @5600, Pico 4, HOTAS & Rudder: all Virpil with Rhino FFB base made by VPforce, DCS: all modules Link to comment Share on other sites More sharing options...
Bio Posted June 13, 2023 Share Posted June 13, 2023 (edited) I decided to give it another look with MSI afterburner. Still in VR, Pico with Virtual desktop at Ultra (2736x2736) SteamVR as OpenXR runtime. A10CII Syria Air-to-Ground mission, just set the plane in autopilot and waited a bit, switched to map and back to cockpit. System: RTX 3070 8gb, 5800x @4.5, 32gb ram, m.2 drive I got more questions than answers. From the screenshot i marked with an arrow where the map switch is done on the GPU usage. Various weird things happen after F10. - GPU usage goes up - FB usage goes down, shouldn't it go up instead ? - VD usage goes down, shouldn't it go up or stay the same instead ? - BUS usage goes up, kind of makes sense but still weird. I probably don't really understand this one - Memory usage goes slightly down. This is super odd - Heavy power usage fluctuation but overall power usage down The last point is the weirdest of all, higher gpu usage but lower and more unstable power consumption? Could it be it's a CPU issue where DCS is trying to do some weird stuff with textures and asks the GPU to do useless work with memory that takes frame time from rendering ?

FWIW, I have a 3090Ti and my this issue causes my Reverb G2 to crash... the tracking still works, but it stops displaying in the headset. I know the tracking works still because of the Mirror running on the monitor... I get this most frequently on Sinai (really the only map I've played since this patch came out) and it's particularly noticeable in the Viggen and F-14. Didn't have any issues in the F-16, and haven't flown the Mirage 2000 or AV-8B to see if it's specifically a Heatblur module related issue...

RealDCSpilot Posted June 14, 2023 Share Posted June 14, 2023 (edited) @Bio Okay, VRAM allocation shows full usage all the time. It's already maxed out, but this is showing allocation only. There is an option in Afterburner to set VRAM usage per process to see the real values like in this older post of mine: It basically shows that the F10 map needed almost an extra of 1GB VRAM to be rendered. I guess what's happening on your end is Windows going into memory sharing mode and never gets out again. It means that ressources are constantly swapped from RAM into VRAM and back at a certain point, when the limit is reached. This stresses the system on CPU and all data paths (BUS) very much. To get a bit deeper you should try to test a simple empty mission, like those hot start instant missions to see if you can start at a point where VRAM isn't used to the max. And also use the Afterburner option for VRAM usage per process. @Whiskey11 Yeah, that's strange with your GPU... But first, you should take TacView out of the equation. Just to clarify, i don't have that problem at all.

Wizard1393 Posted June 14, 2023 Share Posted June 14, 2023 (edited) I have this issue aswell. I've been flying mostly on Syria and with the F-14/18 and Apache. This issue has been around for quite a long time for me. Long before the MT release. It happens often when checking the F10 map and going back to F1 view, the whole rendering is very weird and stuttery and won't go away. It also happens very often if killed and/or respawning in a new slot, same Aircraft type or not. Pretty much always avoiding the F10 map for now due to this. Complete DCS restart is the only thing that helps.

edmuss Posted June 14, 2023 Share Posted June 14, 2023 (edited) Witnessing the same thing on my end, perfectly smooth performance graph and 70-80 fps in the aero, open F10 map and bang 40 fps, performance graph frametimes have trippled in amplitude. Non-recoverable from my attempts barring restarting DCS. There is also the light blooming effect every so often after closing the F10 map, I'm not sure if this is related though? edit: This is very reminiscent of the VRAM overflow that was killing reprojection, it was fixed by a change to the WMR openxr runtime which prevented DCS from allocating ALL of the VRAM so much so that there wasn't enough left to perform the reprojection. During testing last night I saw that the shared GPU memory usage rocketed from the normal 0.2-0.4gb to over 2gb, I think this is what's causing the slowdown as DCS is forcing the GPU to utilise system RAM. @BIGNEWY I very much doubt you will be able to replicate this as you have 24gb VRAM.

edmuss Posted June 15, 2023 Share Posted June 15, 2023 On the G2, the reprojection VRAM overflow was largely alleviated with the advent of open composite removing the VRAM overhead of steamvr. Additionally the WMR runtime changes completely eliminated it. If you have an abundance of VRAM then you'll likely not see the problem, especially with the low resolution of the rift S. It's also possible the the oculus runtime incorporated better VRAM management than WMR did originally.

SimonR944 Posted August 3, 2023 Share Posted August 3, 2023 I would say its hard to reproduce without the same equipment, what i have found though is that disabling XMP and manually setting Memory speed to 3600Mhz - helped with the stuttering a little. My concern is the fact that having a 3070TI is struggling to get 30 FPS in VR on the lowest of settings even in MT. Link to comment Share on other sites More sharing options...

Well I am not expert but would a trk or log file be helpful Newy? I mean I know it might help but nobody seems to be posting those just chiming in say yep it happened to me.. I posted in a simialr thread of this issue and posted my log files but I did NOT experience the stutters or whatnot going from F10 to F1 and back several times.. I am not sure but maybe something with your setups or mods or something..
