Antialiasing

[westr]

I would like some suggestions for VR settings in DCS for the following reason. 
Im running a HP reverb G2. In cockpit I’m very happy with visual quality and most of the time the performance, although this can depend on modules as some run better than others. My complaint is antialiasing around the canopy in external views of aircraft other than that I’m pretty pleased with everything else. I’m able to run most of my modules at a smooth and steady fps even with rain although it’s too much to ask from the F4 and the apache. I currently run DLAA with no upscaling. I find upscale adds to strange wobbly effects around the edges of the aircraft and turning off upscaling after playing with settings over and over is about the best I can get it. I can’t run MSAA it just makes my experience like a slide show. 
I probably should just accept that things run pretty well and look good in cockpit and leave it at that but I can’t help but find it really annoying that I look at external views and the canopy edges of aircraft look terrible, I’ve always liked checking out external views while flying and have done since way back to simming in the 90s. So I’m just looking for some suggestions I guess but without going to MSAA.
 
Many thanks.

DLAA (without DLSS upsampling) is for me, currently the best compromise in VR.  I’ve tried the other options, and felt that DLAA was best

Hi,

there is nothing better than DLAA, try replacing the old library with the current one, they are outdated in games and DCS.

Ok. So your suggesting to download and install a older version?

If you look in your bin-mt folder in DCS world, you will see the nvngx_dlss.dll, click on properties then details and it should say ver 3.7.0, so swap it with 3.7.20 is what I would do.

Ok I’ll give it a try. Thanks.

Anyone care to share why MSAA is not a preferrable option, as compared to DLAA, for VR?  I run a strong spec system 14900 + 4090.  Thx

I can‘t explain it from a truly technical perspective…

I used MSAA x4 for quite a while because when DLAA came out initially for DCS, it had some really bad smearing effect on moving objects. This is now less pronounced and DLAA provides a better quality image overall. Smoother edges and no shimmering on clouds for example.

This is all highly subjective, I guess. Nothing wrong really with sticking to MSAA.

[zildac]

MSAA causes an unacceptable amount of shimmering in VR, it did for me on my G2 and also on my Aero. As others have said, for me DLAA is far better without the artifacts produced by TLAA. TLAA actually looks better, but you end up with fast moving objects “smearing". Try DLSS Tweaks and force the use of preset E or F. There is no need to update the DLSS DLL in the DCS bin-mt directory, unless you want to.

I mainly use the f-18 module and DLAA has a terrible blurry effect on the aircraft's displays. With MSAAx4 the DDIs are much sharper, but I give you that it increases the shimmering of the distant objects.

But I will give DLAA another try with the latest version. Thanks for the hint

I prefer MSAA 2x over DLAA, since DLAA makes the picture very soft. But with MSAA 2x you get more aliasing. Its as always personal preference

So do you run an install file EnableNvidiaSigOverride.reg ?

And you can choose to force preset E or F? or do you add files to your .EXE directory similar to if you use reshade?

I used ovgme so I can easily enable or disable. And used the DLL method with the. Ini file. I'm away from my machine at the moment so need to double check, it's been a while. I also initially enabled debug in the . Ini to confirm it was working and using the F preset in my case. I don't recall adding anything to the registry.

I’ve just always found MSAA really taxing on my system and also get loads of shimmering as well.

could you please eleborate on how this DLSStewaks differs from the original DLAA available by dealt in the DCS settings?

I have read the Github page info and I do not understand a thing... hooks, layers, tiles... 

thanks

Fundamentally, all you have to do is copy the dxgi.dll and the DLSSTweaks.ini file to your DCS bin-mt folder. You also need to edit the .ini file to force the use of the preferred preset (F for me). Below is a screenshot of the files I have in OVGME mod manager for this particular mod, note I only kept the .reg files and executable in the mod but never actually ran them, you don't need to using this hooking method. I recommend you use a mod manager and not just copy the two required files into bin-mt as it's safer and helps keep your DCS install “clean”.

The second screenshot is of my .INI file and the relevant preset section within it. Note I am only using DLAA not DLSS

The only reason for this is to allow you to force a specific preset for DLAA/DLSS, most VR users agree that F (or E) offer better image quality with less “smudging/blurring” etc.

Ok forgive me for seeming really stupid but I've searched high and low through the DLSS tweeks download page and there is no dxgi.dll file, am I missing something? do i need to launch something to create this file? Thanks

Apologies, my bad. I missed a step, rename nvngx.dll to dxgi.dll

Reporting back.

I have tried the DLSStweaks and it's definitely better than the blurry DLAA that I remembered.

The image on the MFDs has a little bit of"motion blurr" but it's barely noticable now, and the shimmering from the MSAA is gone.

And in scenes with heavy GPU load, like over cities in the Syria map, the GPU time-frames are much lower and consistent.

Long story short, now I am a DLAA believer.

Thanks for the info on the thread!

With the latest releases of DCS both the bin\DCS.exe and the bin-mt\DCS.exe run multithreaded. As DCS could now be running the one in the bin directory (depending on what your shortcuts do) you’ll need to copy the dxgi.dll and .ini file to that dir as well.

Try adjusting the DLSS scaling in DLSStweaks. I use 0.9 and get good results.

I have to admit the same and I'm thankful for this thread.  Turned on DLAA (no DLSS) and added the dll &.ini recommended above and my experience is minimal to barely noticeable ghosting/blur but the shimmering is ALL GONE not to mention w/o MSAA turned on you get some nice headroom back on the GPU so I've been able to bump up the render scale from 75% to 100% (granted I'm running my Reverb G2 at 60hz).  I wouldn't have believed it but I'm a DLAA believer now as well.   

[Tophatter14]

This thread has just convinced me to give it a try as well.  MSAA x 4 user as I find the ghosting / motion blur very distracting in DLAA …if I get good results, I’ll report back.
