v1.27.13.0 New beta build today!

[Ianrivaldosmith 5,317]

So, I just tested now using 3090 and DX12 etc…. It’s forcing the card to stay below 8GB Vram usage, so when it approaches 7.5 ish, it induces stuttering. 
ohhhh well, I’ll wait until they reinstate it then. Glad it’s summer!

Could have left it there for us with 3090’s. It worked brilliant. Now I’m just testing it and it’s stutter again on DX12. One step forwards, two back. 👀👀

Even in DX12 it is the same stuttery mess for me, 3090. I think I will leave the beta as it is now even worse than without the beta.

It’s because they disabled DX12 memory manager optimization on NVIDIA GPUs. So it looks like your 3090 Vram isn’t being used, keeps resetting itself when it reaches 7.5Gb, causing a stutter

I guess so indeed. Tried in Realvfr Plymouth, was terrible, it has a lot of loading photogrammetry, which seems to relate to the extreme stuttering, but also on the relatively simple Eelde, Netherlands EHGG, although to a lesser extent.

I have that as well. I'm running 1920 x 1080 DX12 on Windows 11. I wonder if they've disabled it for lower screen resolutions as the majority of people posting so far seem to be running 4K

DLSS is exactly for the people running under 4K - it's an upscaling technology

I am on PC and it is smooth for me and no stutters panning the view in the cockpit.

After some more tests I have to correct what I said before. DX12 is still unusable to me. After Vram gets maxed out FPS goes from 30 to 12 or 13. No artifacts but unflyable. So back to DX11 again.

Not according to Andrew Edelsten, who led the DLSS team in creating DLSS for Nvidia. He said that people with low frame rates and/or high resolutions will benefit from it, because it "requires a fixed amount of GPU time per frame to run the deep neural network ". DLSS isn't enabled if the frame rendering time is shorter than it takes to execute the model. 4K was the deep learning AIs target resolution. Those with lower resolutions will get unreliable image quality.

This was from the horse's mouth, so to speak.

Edit: It's a performance boosting technology. To say it's an upscaling technology is looking at it the wrong way.

Hopefully they are still working on the night light pollution being missing.

Fair enough. I only mentioned it to see if there was any pattern for those (seemingly few) of us that no longer had it available.

See my comment above. It's a performance boosting technology, rather than upscaling technology. People with 4K resolution and low frame rates benefit from DLSS.

Made a test with Fenix in LGAV(FLytampa) and Vram was 12gb on latest beta ( 3090 Asus OC). Will re-check again in different Airport

Yes... still blurry displays with dlls in dx11 and dx12.

 Bad sttuters while panning inside Fenix A320 cockipt.

 

Same

Mine stops when it reaches 7.5gb and just keeps it there.

Which GPU do you have? I'm also going back to DX11 for now. 

[Cpt_Piett 4,652]

Back to DX11 and it's just impressive to see how poorly utilized my CPU is now. From DX12, all cores evenly used to DX11 and only 2-3 of 16 cores being used... Or actually 2-3 of 24 threads.
