P3D v4.3 Massively Improved Anti Aliasing ?

Recommended Posts

So, I have used 4xSSAA since I started with P3D v4.1 as I despise jaggies, shimmery gauges and 'flickering' terrain lighting at night... resembling a swarm of angry ants ! 

I run on a 32 inch 2K monitor - not brilliant but a good balance between immersion and resolution... and of course performance with my GTX 1080.

Messing around with settings yesterday, I accidently set 4xMSAA instead of 4xSS... and OMG, although I could immediately see a few jaggies and my GTN 750 had a little shimmer, it wasn't bad at all... previously, with 4.1 it would be horrific and unusable for me without 4xSSAA.

So, I put it up to 8xMSAA (from 4x), and they are all but gone. Light shimmer at night is noticeably higher than with SSAA, but only in the very far distance.

Is it me, or is this a massive improvement since 4.1 ?

I actually think I'll stick with 8xMSAA now, as my FPS is literally doubled in 3D clouds (Active Sky) along with virtually zero stutter, and I'm thinking I may even be able to consider dynamic lighting.

I am about to double check today, as it may have been a dream.... 8-)

No change, but I have noticed a recent driver release from nVidia seems to have improved MSAA.  Be sure to delete your shaders folder on any driver update.

Cheers, Rob.

Hate to rain on your parade... but MSAA has always been the same along with the issues it brings. You’ll notice it eventually, especially with certain scenery objects.

4x SSAA with DL on has improved, however, and that’s what I almost always use during the day. At night I switch back to 8x MSAA. Like you, I have a 1080.

The new drivers improve MFAA+MSAA as well...

These the same drivers that crash P3D if you set a frame limit in NVI?

Not sure why you would be using NVI with P3d. I thought most had moved on from that. Are you on P3dV4.3?

I only use it for the FPS limiter. I’m on 4.3.

Is there a change in 4.3 as to the FPS? I'm not entirely sure and I don't know if I'm just seeing things, but I seem to have noticed that without NVI's FPS limit P3D is just as smooth? (For me it's smoother with a limit of 30.5 in NVI)

I was under the impression that most are running without the inspector. For me it seems best to set the in p3d frame rate to 30 or so for best results. Keep in mind I am running 4K @ 30Hz so things may be different for you. As with everything else in this crazy hobby YMMV.

Hmmmm..... maybe it wasn't switching properly between modes - I didn't reboot the sim, each time... I know that.

Will check it out again later. Probably just an anomaly, as it cannot just be me !

Oh well, I'll console myself with my new A2A addon and yoke / rudder pedals coming tomorrow.

Here's to 'Uranium Lake' processors running at 10 Ghz !

But, I'll bet we'll still get stutters even then...... nature of the beast no doubt.

If your TV/monitor is running at 30Hz, you don't need to set the limiter in P3D to 30--just leave it unlimited and turn Vsync and triple buffering on. Vsync will limit frames to your monitor refresh rate. 

People like me who are running 144Hz monitors are using NI to set a limit, in my case 36.

I will give that a try tonight.

I am runnin 2 titans 6gb sli

grear peroformance until I hit dense asp4 asca thunderstorms with 8x msaa and performance drops

I have a Sony 4K TV @ 30 hz and one thing I have noticed with 4.3 is that running unlimited with vsync and tb on with complex stuff I now get 24 fps  and with less demanding situations 45 or so fps. Previously it was always the TV refresh rate - 30.  So what has changed here?  Thanks.

On trying this, I actually found I was on 8 x MSSA.  I then switched back to 4 x ssaa, and found it better. Thanks fir the inverse tip!

Lol.... until you find yourself in 3D clouds, whereupon, your SSAA will stutter you to oblivion.

Bruce, are you sure your TV is 30 hz..... doesn't seem right.

TVs tend to be 60 hz capable. Old CRT TVs in the UK were 50, but modern LCD and OLED are 60.

It seems to me that P3D performance depends on many factors, not least the combination of drivers, settings and operating system updates. Some are still on 1803, some 1709 !

Still not sure what is happening on my system, but I was wearing the wrong spectacles the other night. Thinking my 2.5 may make the jaggies less obvious than my 2.75 ! Lol, lol, lol..... falling off my log laughing at this realisation..... !

So there we have it.... best way to reduce jaggies, is to handicap your vision by around 10 percent !

All systems will deliver different results, but on my 4k 43" monitor, running 8SSAA eradicates all aliasing, but of course a big hit on performance. I have found 4 or 8MSAA not as good as 4SSAA so I run with that. I have to admit, I still see small jaggies, but it's no big deal when I consider the alternative 😄

After DL improvement in 4.3 is there still a need to go back to MSAA at night?

Huh? Isn't that like laying in the bed you've made then asking me if you're comfortable?  C'mon man!

I'm using 411.63 on a TitanXP and a 1080Ti ... I use 4X MSAA for 2160p and 1440p monitors.  SSAA will increase load significantly on the GPU side.

Cheers, Rob.
