reported earlier Same graphics settings with different results between MT/non-MT

[WinterH]

Hi all.

I'm experiencing something puzzling that most other people I know aren't.

Multithreaded exe looks a lot worse for me with same graphics settings. No antialiasing seem to be applied with lots of jaggies, and textures look a lot more low res, especially in the distance. Effects such as raindrop on canopy look pixelated. Changing settings/restarting didn't seem to help. Things look as good as they always did if I go back to non-MT exe.

Not the exact same for me, but perhaps the same source of problem.  I have here two captures of the F-16 ready on ramp mission:

Non-MT:  

 

MT:

 

They look very similar.  However, if you look at the original-sized images, you can clearly see some important differences:
- "Shadowy" areas render really differently.  The sides of the tents or the left frame of the cockpit are much, MUCH darker
- Indeed, numbers and textures are less "anti-aliased" (you can see it in the numbers and text
- If you pay a close look at the grey-black separation just right to the RPM meter, you will see that the non-MT version is much smoother, while the MT one presents a much more pronounce "jaggedness" to the rendering solution.

 

So, yeah, great to have more FPSs out of the system, but not in detriment of the quality of the process.

Maybe this is more explicit of what I meant:

I did some tests, and it seems that MT is not respecting the SSAA setting.  If you use MSAA, it works.  Maybe that's what is looking like "much worse" to you? Anyways, I created this bug report:

Anti aliasing not working right would explain most of it in my case, but perhaps not all as it feels like the sim is also too bright, and texture filtering seems to fall off quite quickly in anything but the nearest distances.

I had both MSAA and SSAA at 2x. I'll try to see if using only MSAA or leaving AA to Nvidia makes a difference.

FWIW, specs are:

Ryzen 5 3600

2060 Super 

32gb ram

Hi, I have exactly the same issue, but even with 2x MSAA or even 4x MSAA, the jaggies are still much more noticeable than in non-MT with MSAA off and only SSAA 1.5x.

Another point to note is that if I use re-shade, the MXAO (ambient occlusion filter) doesn't work in MT, while it works in non-MT.

 

I have a GTX1080 and Intel

None of the SSAA filters are working, nor the Motion Blur. They have asked us to turn those off for the time being.  4x MSAA on the other hand, did actually work for me.

I have MSAAx4 and anisotropic filtering x16 enabled ingame and the following via the Nvidia control panel: DLDSR, TRAA multisample, MFAA. DLDSR does work but TRAA and MFAA don't seem to work with the multithreading exe.

I tried to add bin_mt\dcs.exe in the NVCP, without visible success. I expect that the MT dcs.exe is also recognized as dcs.exe by NVCP - so that the program specific settings should be applied regardless which dcs.exe version is running.

Might be the same problem as with Reshade mentioned by bkthunder, postshaders not working.

MFAA works, you need to use the "improve application settings" option, and TRAA should not work, DLDSR might not work because of the removal of the exclusive fullscreen since 2.7.
You have way too much AA that will just destroy your image quality and destroy your FPS aswell, just use MSAA 4x without MFAA and it will look the best.

Well, I tried a lot of configurations and this ended up to be my favourite regarding performance and appearance. Yup, MFAA and TRAA are enabled in NVCP via "enhance application settings".

But I will give it another shot with only MSAAx4 in DCS at both native 1080p resolution and at DLDSRx2.25. DLDSR gave a big performance boost when I used it instead of SSAA in DCS and it works very well in versions 2.7 and 2.8.

Again you should not use that kind of stuff, you can use MFAA but it can make the image blurry and you should not use Temporal AA with DCS... Anyway...

Thanks for insisting, you convinced me! I've tried MSAAx4 in DCS only with both native and DLDSR in single thread and multi thread, omitting the other NVCP AA methods.

It's in fact better without temporal AA and much less shimmering than I remember from previous versions. I've settled with MSAAx4 and DLDSR in multi threading now.

So I've actually found my personal solution in this thread by replacing in-game SSAA by DLDSR

You're welcome, if you change resolution you might also stop using DLDSR since it can use up to 50-80fps in some cases, 4x MSAA at 1440p is more than enough tbh.

Any solution to this problem with atialising with DCS MT? I was going crazy thinking it was a problem with my amd 6800 xt

Im having the same problem and cant find a way around it, spend ages trying every combination of settings and Reshade settings I can think of and nothing has worked. The edges are noticeable in cockpit but far more on things like runway/taxi markings and trees off in the distance and clouds, man do you see it badly in distant cloud layers realy pronounced jagged edges and even pixelated alot of the time with them on Ultra!  Running a 6800 and 5600X Cpu with 32Gb ram.

it's a problem of dcs antialias, i've got your same problem....we have to wait a fix from ED
