DCS 2.9

I’m betting that the model is ready, but some updates to the hose/drogue (maybe physics ala BMS?) are part of the package. Fingers crossed!

I don’t seem to have the option to enable upscaling, in particular DLSS. Is that because I’m running an AMD CPU?

No, but you do need a Nvidia GPU. The setting is called upscaling I think. You can choose between OFF, DLSS, FSR and NIS. DLSS only works with a compatible RTX GPU

RTX 3090ti here. It requires multithreading enabled. I was doing some load time testing and forgot to enable MT when finished. Nice that you can try the different upscaling and color grading values without restarting the sim. I didn’t detect much of an fps increase by enabling DLSS,

Are you CPU bound? I noticed a significant bump in performance, even on quality. I fiddled around with the settings and can get a pretty constant 90fps with some minor compromises on the balanced setting and sharpening at 0.05 but I will probably add some more eye candy again as I can run SSAO and SSLR with ultra visibility range and still maintain 60fps, I was just trying to get to 90fps last night…

Cockpit readability is slightly worse with DLSS but it’s still okay.

Yes. I should have added that I’m in VR (Q3) and that I did get rid of a few stutters enabling DLSS. Funny, I read that some have more stutters enabling DLSS, but I definitely have less in the Sinai map. I was using balanced. Will try sharpening at 0.05.

Been asking for that for a few years now. Crossing my toes too.

Fiddled around on my machine and can’t make sense of the new settings.

i5-9600k at 4.8Ghz, 3060 overclocked 12GB VRAM, 32GB DDR4, all SSDs, Quest 2 72Hz, slightly above recommended resolution at 1.1x (4128x2096). Running the Tomcat on Supercarrier in Syria as that’s my most demanding combination.

MSAAx2: 44 mirrors off, 36 mirrors on
MSAAx4: 36 mirrors off, 34 mirrors on
TAA: 46 mirrors off, 36 mirrors on; unplayable due to blur and ghosting
DLAA: 42 mirrors off, 36 mirrors on; less blurry but still unplayable

DLSS balanced: 52 (unstable) mirrors off, 36 mirrors on; blur factor :poop:
FSR 0.66: 52 (unstable) mirrors off, 36 mirrors on; blur factor :poop: :poop:
NIS 0.66: 52 (unstable) mirrors off, 36 mirrors on; blur factor :poop: :poop: :poop: and vibrating displays

What’s also interesting is that every time I had mirrors on except for MSAAx4, my frames would have periodic “reverse spikes.” I would be locked at 36 for a few seconds with frametimes flatlined, then a couple seconds of frametime activity and increased framerates to the low 40s, then settle back down to flatline at 36; repeat ad nauseam. Also, mirrors on would throw me from GPU bound to CPU bound.

For now I’m probably going to leave my settings as they were before 2.9, MSAAx2 seemingly the most stable though also lots of jaggies.

I’ve heard similar things from people with older CPU’s, you are not alone. 9000 series Intel CPUs are slowly starting to show their age and unfortunately no amount of overclocking can fix that.

A buddy switched from a 9700k to an R7 7800X3D with 64GB DDR5-6000 and the difference for him was night and day. IIRC he still has his 3070, so it was only a mainboard, RAM and CPU swap, he kept everything else the same.

Good info

Oh.

My.

God.

Tomcat replay tracks work!

DLSS also looks amazing in 2D. I can upscale to 4k resolution with max graphics still locked 60fps for filming. Now I just need to figure out the best VR settings.

That’s huge.

Nice touch, the cockpit lugs in the Viper pit are now animated.

Edit: Played around with the new AA settings for a bit. Probably huge for very high resolutions, at my measly 1920x1200 setup there’s no real benefit to it, though. MSAA, while having some aliasing artifacts occasionally just leaves the pit vastly more readable. Thankfully it’s back in working order now.

OH MY!!! Now Thisss is progresss. Im waiting painfully… patiently… only four more Iraqi hours to go… 0.6MB/s… kill me now
Real happy about playback though

just tried the 109 and spitfire over Normandy 2
DLSS set to balanced
was getting a smooth flight with FPS mostly in the 70s, this is in VR
did notice some ghosting around the clouds and if you were up close with a target
but overall not bad


bit of a botched landing and nearly hit an 88 :grin:

I am getting occasional long pauses in both single player and multiplayer. In MP, the pauses are long enough to get me kicked for a ping time limit. DLSS looks terrific in VR!

So I really like DLAA. Its appearance vs MSAA 4x is nothing major but it feels like less of a performance hit.
TAA was not useful, too many artifacts and things would happen like the tip extenders on the E-3 disappear when you first move the camera but then appear a few seconds after you stop moving it.

However, while DLSS seems to improve performance a bit there is a shadowing problem with the planes that I am not willing to deal with right now. I was running the Mirage 2000 instant action bomber intercept in PG for anyone with the same modules who wishes to replicate my experiment.

Most notably the Mirages on the tarmac left 2nd “ghost” shadows at certain camera angles that were offset from the main shadow by a significant amount, like there was a 2nd sun. This only occurs at certain angles, move the camera and this shadow would itself move around and even disappear at others.
On the E-3 itself, when looking from the shaded side of the plane at the sun, all is fine. As you move around to the sunlit side a shadow would appear on the side of the plane until it covered almost the entire lit side of the plane! Pan around and it would vanish.

I tried turning SSAO, SSS, and secondary shadows on and off and this was independent of them. Turn off DLSS and this goes away again independent of the shadow settings.
I will add I have a RTX 4070 with the latest nvidia drivers and an i7-12700k without any OC.

So for now I will use DLAA and all the shadow settings but not DLSS. As I’m getting a nice 100fps with vsync on (because I have a Gsync monitor) anyway, I see no need to turn it on anyway. I’m not concerned as this is the first DLSS release for DCS and I’m sure later updates will correct this.

Oh and I will NOT use FSR or NIS. Both of them had awful artifacts, such as looking at the same E-3 in the clouds the edge of the plane would warp and shimmer and look like a hologram projected over the clouds at times.

FSR, NIS Both use Spatial w/o motion vectors,
TAA Should be using them, but looks like it’s not.
DLAA is AI assisted TAA
DLSS is AI assisted DLAA rendered at a lower res and upscaled.

I’ve played around with so many settings and just haven’t gotten anywhere; still stuck at 36fps. In order to get MSAAx2 clarity with DLSS balanced I need to max my Quest 2 resolution, and set DCS PD to 1.5, and max out the DCS sharpening. And then I’m at like 20fps.

For best clarity and performance I’m stuck on old MSAAx2 settings with lower Quest 2 resolution, at the cost of jaggies.
For best upscale compromise with very smooth performance even at 28~30fps, I have DLSS balanced and sharpening max, Quest 2 resolution max, at the cost of ghosting and barely readable gauges.

I had finally some time to check out the 2.9. It got so stuttery for me it’s basically unplayable, weirdly 2.8 run silky smooth without any freezes (2.9 also runs smoothly when it’s not stuttering) and now it’s just ridiculous. I’m often getting 180 fps and bam, 1-2 sec freeze. I tried different graphics settings with DLSS on / off, and even tried running on both executables, same story…
