DLSS "update"

[PacFlyer23]

This may be old information, but I ran across a YT on the DLSS 3.6 update this week. It's for MSFS players and points out that you need to also update your Nvidia Driver - an update was release this week right before 3.6. Not sure how much of what is said is applicable to DCS, but the update of the Nvidia drive makes sense.

The best thing to eliminate ghosting is not to use DLSS at all.

This DLSS looks ok only if you’re already getting a high enough frame rate that you don’t need it. I can’t see how it makes any sense. DLAA actually looks good but again only at a high FPS

Even though my frames are maxed out most of the time, turning on DLSS makes my graphics card run cooler with no ill effects so I run it.

MSAA is a big performance hog and the AA in VR is not very good. With a 4070 running VR I need to either use DLSS and maintain 72 fps or MSAA with 45 fps and reprojection (does not look great). 

DLSS works better with a higher res so I push my resolution to 1.3 and apply DLSS-quality. This gives me good frame rates and a similar quality to DLAA with less noticable ghosting. 

Quest Pro at native resolution is about 2700x2700 pixels. 

2700x1.3 = 3510x3510

4320x0.66 = 2317x2317

Overall that works out that DLSS should have 15% less workload than DLAA.

So just tried this, making sure to use the latest Nvidia drivers and cleaning out the FXO and Metashaders folders first. Everything is buttery smooth, though that's a bit subjective cause I didn't do a real before and after comparison. Hitting a constant 120FPS with graphics absolutely maxed at 3440x1440, even on a loaded carrier deck with 4 hornets on the cats. I use the Save Kasbah mission https://www.digitalcombatsimulator.com/en/files/3308295/ as my benchmark. Not bad.

Not sure what temps you get but a GPU can run at about 80d C with no trouble. But yeah the reason DLSS looks good for you is you’re already getting a high frame rate. In DCS it’s hard for me to evaluate DLSS because I’m overkill on GPU. But in MSFS where that game will tax even my specs DLSS looks freakin awful! No thanks. It might be a ok way to boost from 80FPS to 120. But trying to use it to get from say 30 to 60 is pointless. Now the frame doubling feature (DCS does not have) can kinda look ok depending on the situation. I hate the idea of games being designed to be unplayable without resorting to DLSS.

I save about 6-7 deg Fahrenheit with it on. Since I'm usually flying for several hours I'll take any temp reduction I can get.

It keeps the room cooleronce long ago I had two SLI cards blowing 180d air out of my case.

Think I'll stick with MSAA 

Edit: Wags confirmed DCS is FSR 1.0

 how does one use DSR in VR?  does it even apply to VR?

DLSS "versions" are not game or driver dependent

[Bucic]

Has anyone compared "dlss vs normal" AA performance normalized for a comparable quality on an RTX 2070 tier system? I'll be frank. I don't feel like doing it myself. I set it like that (see the screenshot) and let it be.

EDIT:

Here's the missing screenshot and my specs.

Intel i3-12100F

RTX 2070 8GB MSI

64 GB RAM

Motherboard MSI PRO B660M-A WIFI DDR4 (MS-7D43)

I have. I don't have the exact fps or anything but it's a big difference. I use VR. With DLSS I can run a steady 72 fps. With MSAA I need to run 45 fps and use reprojection.

Thanks. The unusual factor is I'm limiting FPS from ~120 to 60. And honestly I got a bigger improvement from the terrain engine update than from DLSS. Not in the form of FPS but smoothness. To put things into perspective my video recordings turn out smoother now than pure gameplay previously with no video recording.

Coming back to DLSS, the ghosting is really noticeable in 1440p.

there are drivers that take advantage of some features at a low level, and some of the DLSS functions are tied to the GPU Driver version.

you can't drop a DLSS DLL in a \bin\ folder and expect all the features to work when the GPU's driver doesn't even know what they are.

But don't believe me, drop a new DLSS dll in your bin folder and run the RTX40 Series launch driver from several years ago and tell me it's not causing problems.

nVidia themselves state minimum recommended driver for each DLSS version, they are independent libraries but they rely on specific driver level instructions as well.

Is there a page with that info? I run studio driver. They're not annual. I received 2 updates just this month.

My preferred setting is DLAA without DLSS.

MSAA causes too much shimmering using 2x, but 4x only helps a tiny bit with worse performance.

DLAA is more blurred looking at the distance, but I prefer this over shimmering with MSAA. I tell myself that it is haze, since IRL this also causes a kind of blurriness.

I have not tried DLSS with the new DLSS version, since I get good performance already with DLAA.

I prefer DLAA but sometimes have to use DLSS to boost performance. You don't notice the difference too much when you are dodging bullets.

Can you share wheres that info?

[skywalker22]

I switched to DLAA yesterday, which causes some shimmering on moving objects (at the back of them), but its not that bad as in DLSS. I tired only on monitor, have to test it in VR today as well, specially regarding performance, in comparision to MSAA.

3.7.0 is out. I have just try it out in Kermal Campaing...still ghosting but it works.

[Richrach]

I have been through and done just about every combination of everything recommended on the forums and elsewhere to improve frame times and frame rate.

 

What I have found that works best (i5-12600KF, RTX-4070, 64GB DDR4, Pimax 8KX set to large FOV, 1.3 render quality) is turning everything off in NVIDIA control panel except CUDA, Low latency, and Vertical sync to fast.  DLAA, Antisotropic filtering 8x in DCS.  No ghosting, solid frame rates at 50 (which I limit in DCS) and great playability.

 

No OC on the GPU, my CPU is OC at 50 all cores, which is not as high as it can go (52P/41I), but going higher does nothing for VR and heats up the CPU too much for me. 

 

Done chasing the latest and greatest fad.  Most are too specific to a particular setup.

 

One fella's observations.

Any difference to 3.6? 

[Mamakin]

I came from 3.5, looks very similar. 

[rfxcasey]

While I definitely sympathize with those having ghosting issues, I'm more concerned with any performance gains. I haven't done anything other than anecdotal observations, curious to know if anyone else has found a performance difference between DLSS dynamic-link library versions?
