SSAA unuseable

Title says it all. With SSAA set to 1.5, performance is reduced a phenomenal 50%, and image quality is horribly jagged. With SSAA set to 2, performance is unplayable and image quality just a little better.

I use MSAA 2X on 1440p monitor.

Tried SSAA 1.5X instead of MSAA, but with a huge fps loss and worse image quality.

Where there is the most need to use the smoothing of the jaggeds is the cockpit, unfortunately the method of SSAA gives the minimum effect with a huge loss of performance!

I imagine thats why its made an appearance in the Open Beta so it can be tweaked and optimised

I used it for some screenshots and managed FPS in the high 80's so it does work and obviously your rig is slightly better than mine @davidzill

You would expect a massive performance loss. Its quite literally breaking your image up into 1.5 or 2x the pixels and then applying AA and rendering back into the original resolution.

Gave 1.5 a try in NTTR and PG...

I have a mid-grade to maybe a hair below mid-grade rig where I usually get 45-55 FPS with 4X ASF and MSAA OFF.

NTTR: Minimal FPS Hit with a slight quality improvement

PG: Minimal FPS Hit with a noticeable improvement in quality BUT there is a rendering oddity when out over the water. There is a solid line running perpendicular to your line of flight that passes just about through where your body is in the cockpit (A-10C) with water in front of that line showing lower quality than water that's in your view behind that line.

That is strange, my fps were ~50fps with the Ka50-FreeFlight, WQHD, maxed out settings and MSAA4x.

With SSAA1.5x it went to 70-75fps same spot on map, MUCH BETTER glimmer, actually non existent with Extreme Visibility. Very very nice, a good balance indeed.

SSAA2x is overkill, 25-28fps with superb graphics....meh...maybe the next GTX or Vulkan will make this usable.

Overall, I love SSAA1.5x, it's the right sweetspot between LOD, clearness and performance for my needs, YMMV.

For me SSAA at 1.5 or first stage gave me 10 - 15 fps more compared to MSAA set to 4x.

For my aged R9 280X this is a plus about 50%.

And it does look way better than MSAA. The MFDs are much better to read an text is crisp sharp.

Quite weird the performance of SSAA is so different...

SSAA is Supersampling.

Think of it this way - if you're running 1080p, and have a video card that is more than what's required to power a 1080p monitor, SSAA is a good option.

If you're already running at a higher resolution that is close to or already maxing out your GPU.. SSAA is going to give worse performance.

yep

yep

Nope.

I clearly have a rig that can run DCS in higher resolutions and I'm normally between 40-60% card utilization. If I turn on SSAA at all it's constant jitters, <20fps, and no noticeable improvement of image quality.

that doesn't sound contrary to what i said... im at 4k.. SMAA is not practical... which is what Headwarp was saying... we concur that it is practical for lower resolution monitors where the GPU can handle super sampling a lower resolution.. it is not practical to super sample high resolution because no current gpu can do that effectively... so, that it what is meant by yep..

Yes, but I accidentally left out that I'm on a ten year old 1080p monitor. According to the above logic SSAA should be perfect for me, but it's not. It literally makes DCS unplayable. I've never seen a bigger more consistent performance hit from any other settings option.

Edit: I mean, it's nbd. I just turn it back off, msaa back on, and I'm back in business. If ED decides to force SSAA then we're going to have a problem.

If You understand was SSAA is, then You'd know, Not to use SSAA on anything above 1080p.

Especially On a 4K Screen.

SSAA Is Super Sampling

So:

3840x2160 x 1.5x = 5760x3240

3840x2160 x 2.0x = 7680x4320

If You understand was SSAA is, then You'd know, Not to use SSAA on anything above 1080p.

1) Ok, the reason you're seeing all the comments is because people don't understand what SSAA is or how to use it, and ED hasn't provided a lick of guidance or explanation . A lot of us are basically getting what we can from wikipedia and anonymous 'forum experts', which of course is often contradictory or just plain wrong. Not everyone here is a software developer nor should they have to be to enjoy the sim.

2) After some testing I discovered that it wasn't working for me because I'd forgotten to turn MSAA off. 2xSSAA + 4xMSAA = No Workie. Mea culpa.

3) As expected, I still get noticeably better performance with MSAA. With SSAA on, flying over Dubai turns into a stuttery mess. The sea floor also doesn't render properly. Areas of the sea floor show up as weird geometric patters that seem to be tied to cockpit shadows, in other areas the sea floor isn't visible at all. I'll try to provide some screenshots in a little while.

4) If SSAA is only for lower res monitors, takes a huge amount of resources, negatively impacts performance, and provides negligible graphical improvement over the alternatives...what on earth is it for and why has it now been implemented in DCS?

It actually does show good results at WQHD too. The quality it delivers is by far superior to MSAA4x with only 1.5x.

I've got a 1050ti and a 1080 monitor, does this fit with my situation ? I'm not losing any frames I don't know if i'm gaining frames like the guy above with the similar AMD, but i'm getting better visuals with no performance drop.

sounds good to me... at 1080p your gpu can apparently handle the task and provide better image quality!!.. happy to hear about a 1050ti getting good results too.

I agree,

SSAA 1,5 on a 1440p monitor , i7 7700k, 32gb ram, 1080ti, all maxed out, superb quality :)

It would also help if ED and NVIDIA worked together on an official updated NVIDIA profile so MSAA/SSAA worked effectively with shimmering and jagged edges, The Profile listed with NVIDIA drivers Digital Combat Simulator Black Shark is a dinosaur and needs attention to bring it into the 21st century,....

Don't always think only at Nvidia, there are also AMD graphics cards and soon also some from Intel.

This has to go well everywhere.

Yes but regardless of which product you use, the normal etiquette is for game developers who release a game/upgrade graphics engines etc, normally have no hesitations in creating a profile in cooperation with GPU designers ie NVIDIA/AMD/Intel etc, and keep it updated as the graphics engine/hardware evolves.

The amount of $$ we invest in a Simulation like DCS and not too mention GPU hardware we buy, i think its fair for us as end user customers to expect and get a working profile much like a another flight simulation i use provides, we end users fought for 2 years with that developer and sent thousands of feed back requests and open letters, heck we even spammed the Geforce Experience feed back tab for months, posting on Nvidia forums and the developers forums as well!

End result was an updated profile and ongoing updates by NVIDIA as that sim evolves.
