Any improvement w/ cloud impact on frame rate when using 4XSGAA in V3?

Recommended Posts

just got V3 here, and AA is working much better then V2.4 I dont even need 4XSGAA clouds look stunning.

So you believe they changed AA in V3?   And why may I ask did you comment that 'colds look stunning'?  I never thought any kind off AA had any significant effect on clouds one way or the other.

I see an impact with just 2X SGSAA. SGSAA performance doesn't seem to be impacted as severely by clouds in FSX, where 4X SGSAA barely makes it sweat, so I wonder what gives here. Is it practical for LM to somehow tag the cloud sprites to be ignored when antialiasing is active? Is that even possible?

Has anyone tried the new Rex soft clouds in V3? I use 4XSGSSA in NVI. There's a little bit of drop with heavy clouds, but not too bad. However, you need NVI for 3rd party stuff. The default V3 works fine without NVI.

Still using 4xSGSS NI setting. PMDG cockpits look sharper. Same with A2A C172 .Until now I did see much perfomance difference with v.5. On heavy weather I turn off volumetric fog and terrain shadows, this helps a little, as before.

For me, 4xSGSS is a must-have to control shimmering.  With P3D3 on a 4790K at 4.6 GHz and a 980, 4xSGSS worked well (locked at 30 fps) until a lot of cloud cover comes into view, at which time GPU usage spikes rapidly up to 99% and frames drop intermittently into the low 20s, and some regular microstuttering begins due to the high GPU load.  I'm using an SHD monitor at 2560x1600...a 1080p monitor with half as many pixels per frame should fare a bit better.

 

Last night I swapped out the 980 for a pair of water-cooled overclocked 980Ti video cards in SLI, and now at same settings with 4xSGSS both GPUs peak at ~80% and frames stay pinned at 30.

 

So clouds+4xSGSS is still a heavy hit in V3, but the good news is that you have the old option of reducing settings (why leave shadows on in heavy clouds anyway?) and now you can actually use the brute force of added GPU power to your advantage.

Am using 2/4xSGSS since day one of v2.x so as for v3. With REX soft clouds i dont see any mayor drop in performance on my 5820k SLI 980 here. Both 980s have a load of around 60% when flying through clouds. 

 

Checkout this video. Besides the effect artefacts induced by SLI in v2.5 the performance isnt that bad concidering its the NGX im flying here. In v3 the SLI induced artefacts are history and the performance is a bit better. I fly on a BenQ FullHD beamer.

I can only compare from 2.4 or FSX as I did not have 2.5. But the AA is working better and much smoother then 2.4.

 

As far as clouds go, the reason they look so much better is because before when you flew through them and looked to the side you could see all the different layers one after another as it made up the cloud. NOW its just cloud, any direction, no visible layers. just like in real life as you fly through the clouds. Never had that in FSX.
