P3D v4.5 Hotfix - Aliasing Increased ?

Recommended Posts

Definitely seeing more aliasing with same settings as before. Need to increase from 4xSSAA to 8x to smooth out jaggies and shimmer

Just me ?

hmm, thats worrying. If thats true we would have to sacrifce the FPS we just re-gained with HF1 to maintain visual quality.

Are you guys comparing 4.4 with 4.5 HF1 or 4.5 with 4.5 HF1? I'm wondering because i recall something about v4.4 PBR shimmering was fixed in 4.5 (i skipped 4.4 entirely due to flightsim hiatius). I just hope they didnt have to roll this back in HF1 just to fix the FPS issues introduced with 4.5

It wasn’t fixed in 4.5 anyway.

Ok, maybe not "fixed" but "significantly reduced" perhaps? Or really no improvement at all?

At least we still have 4.4 —

I set 4xMSAA and FXAA in P3D. 

I have no jagg, no shimmer, and even the shadows are smooth. I don't get the blurry cockpit panels either, all crisp.

Nvidia Driver 430.64

I also gained 5-10 FPS with the hotfix

That's funny I just turned on FXAA for the first time since getting p3d. It's very nice and smooths everything out. Not as blurry as it was when I used the first version p3d.

Wow, always avoided FXAA as so many people said it made things look blurry.

Just tried these settings and as you said I had no jaggies, no shimmer and the

smoothest flight I have ever had in P3D. Also the bonus of being usable at night

with Dynamic Lighting. Textures were also the sharpest I have seen with no

autogen popping. I'm a very happy bunny. Cheers.

I upgraded back to 4.5, and applied one tweak suggested, tuned it a bit, and another I used with FSX.

I changed my AffinityMask Value to take the load off of core 0, because that is the core that windows uses for housekeeping, etc..... 

I used the Affinity Mask Calculator to turn P3D away from core 0, found on this website:

http://www.gatwick-fsg.org.uk/affinitymask.aspx?SubMenuItem=utilties

That helped smooth out some photoscenery lags I was having, since I use a lot of that.

Then I adjusted my FIBER_FRAME_TIME_FRACTION=0.11

This seems to help although I really felt one of the earlier 4.4 builds, or maybe it was the 4.3 build, was where I had the best performance.

There were many posts by savvy people I trust, that it was a myth on the current O/S as Win10 knows much better than you how to distribute the load for its own housekeeping. But enjoy what it runs best for you, of course. Just consider that there's no 'theoretical substation' for it in Win10.

Pretty much the same experience here except that my Nvidia Driver isn't quite as up to date as yours.

Excellent finding @pracines !!! I have the 425.31 and I see the same. It should have to do with the latest hotfix. Very good news.

Ever since dynamic lighting was released, I've avoided SSAA because of the massive hit to FPS using SSAA.

Like @pracines, I've been using 4xMSAA with FXAA with very little impact to FPS.

There is a slight blur added to the picture, inherent with using FXAA, but it's very slight and not as noticeable unless you are zoomed way out on a panel trying to read very small text.

FXAA makes cockpit displays and panels look like garbage, no matter what the zoom level is. Yes, it's probably worth the trade-off to get rid of the shimmering, but at the end of the day, P3D has the worst anti-aliasing options of any modern game. Just bad all around.

Purely subjective Chapstick. Distance from instruments, changing the size of the text, needles, etc., directly correlates to how much of an effect FXAA has.

One man's garbage (trash) is another man's treasure.

You were right Dirk, after I did more benchmarking I realized my Affinity mask tweak was just a placebo effect, 4.5 just performs a bit better for me than 4.4 did, is stable for me as well.  I measured about ten to fifteen percent improvement, and more smoothness although I keep my fps locked at 35 or so.  I am not one to waste time on tweaking, my settings are as they are, they give me satisfaction with the sim in all of my add on aircraft, especially the Carenado Citation 550, my fav flyer in both P3D4.5 and Xplane11.34.  I still recommend both sims for those with room for both, and RealityXP for those who want a good flight management system that is befitting GA aircraft that support it in either sim.

 I also recommend the latest Nvidia driver as well for both sims.

FXAA still blurs out scenery badly.

I don't see any aliasing issues with 4.5HF except some smaller jaggies on PBR textures (PMDG 747 for example). But this was also present in 4.4./4.5.
