I'm having several issues at the moment, with a 4090 + 12900k cpu + win 11, i didnt think they were there before but attempting to use the newly somewhat supported motion smoothing makes them obvious.

If i go into VR and back to 2d, the frame rate will drop in 2d and then in VR as well.  If i use anything but default aircraft i seem to have a good bit of stuttering (in Motion smoothing/vertical sync mode though).
Reference area is eglc with orbx landmarks + default baron, scat clouds, yields  50-51fps in VR (without motion smoothing/prediction)   - 37ppd and dlss qual, no openxr toolkit, dx12, motion smoothing on, vertical sync at 30;
** this same test initially in 2d is 80 fps at 4k with the screen maximized, after vr and back its 70 or less.

I dont use the openxr toolkit because i seem to lose about 5 fps without even setting anything in it.

The clear issue is going to say the 310 milviz or even the justflight turbo IV or similar, it causes motion smoothing to be stuttery.. also dropping to 35 ppd didnt seem to help, there is a clear stutter every 5 seconds in VR at least (probably because it goes below 30 fps, cant tell easily the old shift z is no longer working in su12).

I tried reflex on/off (in nvidia cp and sim), no change.  I do have rolling cache back on now (maybe part of the issue unsure, 10gb)

I also noticed even areas like default KPIT in the 310 milviz will sit around 57 fps on the runway with scattered clouds, in 2D, shocking considering the default baron is around 80 fps at intense eglc)

Any thoughts or suggestions or experiences?

I've read in some other threads that FSUIPC needs to be updated after SU12.
I don't know if that's the issue you have though.

Ah, i havent updated that one yet.  I really wasnt utilizing it.  Not updating it can lead to fps issues?

Yep that's what I read. I don't have FSUIPC myself so I can't test, but would be worth checking out I think?

This thread has some pointers on how to update it without causing any issues:

Well uninstalling fsuipc may have gotten rid of the weird sudden every 2 sec stutters i had.

However, setting aero to 37ppd and motion smoothing mode and no openxr with dlss quality, i can only achieve say an average of 22-30 fps at eglc area, though really it "feels" more like 30 now, with an occassional freeze stutter thing which i believe that part is a known issue, this is with the turbo Arrow III however, not default.  In default baron its a fixed 30.  (hags off)

I also turned off rolling cache to reduce the likelyhood of stutters. 

Same deal around kpit, though a bit worse, more often at 22.5-23 than 30 at times, which is really strange to me.

Strange that even the Turbo III drops the frame rate (eglc 65 fps vs about 80 in the default baron at 2d mode maximized 4k).

Anyone else have this kinda fps drop (in 2d too) with non default aircraft, maybe its just par for the course and i should drop to 35 ppd and use the openxr toolkit.

EDIT: another test of laguardia NYC in the c310 milviz.. im only getting 30 fps at 37ppd on the runway with scat clouds DLSS quality AND openxr fov enabled (35 fps if 35ppd, which looks horrendous suddenly), i get about 60 fps in 2D on the runway.

Something is really wrong here, i think i should be getting more like 45 at 35ppd at the very least.  

EDIT2: i thought i had tested without addons, well at least at EGLC i did, now with no addons, NYC laguardia, i can get 54 fps (with cas on) or 57 fps without at 37ppd in the C310 which is more demanding than the turbo III, so I have a real baseline and at least in this region need to figure out what addon tanked things to around 30-35 fps.   Needless to say, 30 fps motion smoothing mode here is brilliant now as is.

I don't have fsuipc but I do see this.  If WMR is still.active after I came out of VR mode I experience poor performance.  I have to unplug my headset then it usually it's ok.

UPDATE:  it turns out it was the TDS GTN750, if i disable that, my fps in 2D jumps 10 and my fps in VR went from 30 to 55 at laguardia nyc.  (This in the c310 at the very least). 

Not sure why or how to correct it.  I’ve seen comments about disabling Defender or adding exclusions, i dont use defender, as i use eset and eset has been tested as being paused during these tests. Also nanovg is enabled in experimental features.  I tried disabling the tds gtn 750 and enabling the pms gtn 750, despite using the same gtn_simulator.exe the pms has no degradation

Get in touch with tds support.  They have an experimental update that seems to work well for me.

Is there a direct link to download the experimental update? I tried finding it, but Discord is a maze to me.

Thanks,

I tried digging around on discord, couldnt find it, nor on their main support forums.  I did post the question both places however.  Maybe support will reach out,

No it has to come from the support team.

Try their support forums then

http://forum.tdssim.com/forum-2.html

I'm waiting to hear back if there is an experimental build.

 

But, in meantime i guess i should have asked if anyone with the gtn750 from tds actually HAS an issue when using the aero.  Maybe something isolated to my hardware combo im beginning to think. 

***Or more aptly, anyone with an aero + tds gtn run just fine in vr on win 11 with the 4090?
