DLSS 3.0, am I missing something?

[Pilot53 551]

With my 4090 and 10900k im clearly cpu limited, so I thought turning on frame generation (dlss 3.0) would help my fps, however they stay exactly the same whether frame generation is on or off.  What am I missing here?

I think you have to use a third party fps tool to see it. It doesn’t show the actual number in MSFS.

If you have a VR headset, then you will probably see higher fps (because the resolution required is so very high in VR that the GPU is likely to become the bottleneck). 

DLSS is probably not going to give you more performance if the GPU is not the bottleneck. Your gpu is so grand compared to your cpu that the gpu is only seldom going to be the weak link in the chain.

You can also turn up the LOD (even higher in usercfg.opt). That should make you gpu limited and that's where DLSS 3 will probably shine. Or run 3 monitors side by side in order to tax the 4090, LOL.

You could google something like "will fps be increased with dlss if cpu limited?"

By making your system cpu limited like turning up the various display options wildly high, you will probably get a fantastic image and not give up any fps. I'm jealous!

Watch this video…about 3:30 in.

Wow, great video. I learned something there (3:30).

[Fielder 3,820]

but in video description he says: "Note DLSS 3 is not compatible with VR at the moment. Frame rates will be limited to the maximum refresh rate of your monitor, in my case 144Hz."

As I understand it, the only version of MSFS 2020 which is DLSS3 compatible is SU11, which a beta version.  You have to sign up for beta testing to access it.  I tried it, but my program crashed.  I'll wait till November eventhough I have an RTX 4090 video card.

Pretty amazing!  I read that at some level RTX3000 series will have some support for DLSS3 in which case we might see 3090/3080Ti hitting 50 or 60FPS since the differences between 3000 and 4000s w/o the DLSS3 isn't all that much. It's the least Nvidia can do since they launch these beasts then pretty much sell out in a couple of days.   As is typical he's only showing 8.3Gb of VRAM in use despite the 24Gb, and in DX12 no less.

Ah that clears it up for me thanks.  Regarding VR, does it do anything at all or is it simply just disabled for VR?  I notice that under the VR specific settings tab there is not option for frame generation.  That would be a shame if it was not working in VR as VR is where it stands to provide the largest benefit.

Again, I'll try to explain how the 4000 series cards can always give you a performance boost (when the game in question supports this new tech).

The DLSS part of the technology is doing the upscaling from a lower render-resolution up to your monitors resolution.

This is not where the extra performance comes from. The fps boost comes from enabling FRAME GENERATON.

You can do that with or without DLSS active, but it requires a 4000 series card.

For example, lets say you get an avarage of 75% increase in fps with frame generation on. You'll get this 75% increase NO MATTER THE SITUATION in the sim.

If you we're in a situation where you got 100 fps before, you'll now get 175 fps.

If your got 30 fps in another situation, you'll now get ~55 fps with frame generation.

This is because the normal frames are generated exactly like before, you just get the extra tensor core generated frames FOR FREE.

once the air clears and Nividia makes their money on the 4000 cards, I am sure they will extend all these benefits to 3,000 cards, with an update on their drivers.  First the 4080's would come out, and then 4070, 4060,, just my thinking.

Mine too, and if they don't enable some of this for folks like us who paid dearly for 3000 GPU I guarantee I will take a stronger look at AMD next time.

And after you’ve finished your stronger look, you’ll still end up with a nvidia in your system haha. They have us by the balls.
