Sim Update 10 beta is out!

[Suff1xed 18]

I’m having some performance issues. Goes from 60fps smooth in DX12 1440P Ultra to 30fps where you can feel some stutters  

This is with a couple of different aircraft. 
 

Anyone else? 

[pilotter 284]

I have missing tiles, or loading late on top of scenery in DX12.

Anyone else think that DLSS with a 3090 at 4K is pointless? Better to run at native res 100 render scale TAA?

I think you're right. TAA vs DLSS at 3090 and 4K = no discernible difference in fps. 

Well, that's perhaps too general a statement, as I haven't really tested with/without DLSS in a number of different scenarios.

Well, I might have to reconsider my last statement. Performance may be similar - but GPU usage seems to be much less with DLSS. From a quick test in the Cessna 170 at 3000ft near New Haven, GPU usage is around 70% with TAA and 50% with DLSS. Less usage, less heat, less fan noise. Or more headroom.

What about image quality and especially sharpness, with DLSS?  I've got a good GPU so IQ is top priority and I really don't like overly soft edges of objects.

Or, you will become cpu limited. I’d rather be gpu limited, it’s smoother. More heat or power? These cards where designed for that, so it’s fine by me.

In the Piaggio 149 I had double power controls in DX12

Then you might find that TAA works better for you. If I look hard enough, I do notice that IQ is slightly more blurry with DLSS. 

Another issue is less object shimmering, although I'm not sure whether that's a feature of DX12 or DLSS. Or something else..

Sure. So far I haven't been main thread limited to any meaningful degree in SU10 beta though. But I also upgraded from a 10900KF to a 12900KF...

Isn't TAA the best possible image quality you can get?

It suppose it depends whether you are running at 30 FPS or 60 FPS and how complex the scenery is.  My 3080Ti can't quite manage 60 FPS at 4k in TAA, but can in DLSS, although then the flat panels have a few problems with blur.

Due to the heat in the summer, I am running at 4k DLSS at 30 FPS anyway.  The GPU is cool and quiet, and doesn't heat the room up as much.
I tried running 45 FPS as a compromise the other night (set to 60 in sim (or 100% monitor refresh rate if you like), monitor set to freesync ultimate, and RTSS set to 45 FPS.  It wasn't working - it seemed really choppy, and worse than 60 FPS - strange!
I have had it working before with older drivers and TAA.  I notice there is a new version of RTSS so I might need to give it a go.

At iniBuild's EGLL at the gate in the FBW A32NX: 12.3GB

This is with all settings maxed out except terrain LOD at 200. 

EDIT: 15.1GB when using the drone camera to overview Heathrow. That's the value reported in dev mode. 

Great, my 3080TI is max out at the same scenario which confirms my initial thought when using DX12 after reaching max VRAM it will create artifacts. At least not CTD like in P3d  

[MrFuzzy 2,124]

This VRAM issue must be fixed by Asobo, not many people have more than 12 GB of VRAM...

[March Hare 720]

It doesn't make a lot of sense for VRAM limitations to create artefacts. It suggests a different issue, and any observations about VRAM usage are possibly coincidental.

When you run out of VRAM, the game will usually start stuttering and lagging, because it will switch to system RAM (slower) and page file (even slower) to process the image data, doing more juggling with other data too. Rendering something altogether different implies a software bug of some kind.

Either way, so long as it's officially reported, Asobo can start trying to recreate the issue and debug it.
