This might be a thought but I am starting to see a theme here maybe is the Titan video card the answer as I have not seen any complaints from those who do have one - I know that not the majority - just a thought as I am not seeing any issues mentioned here at all

I have a GTX680 and an ancient i7930 @4.2 Ghz, but have managed to hit a stutter free 30-50fps sweet spot. Will post my settings when I get home if it helps. 

Titan here as well.

 

P3D runs pretty well @4.3gHz with overall pretty good performance.

 

I run photoscenery pretty much exclusively which could be responsible for this.

 

No trees + no autogen = great performance has been my experience back to FS9.

Well, this is interesting.  I tried testing with some other airplanes in 2.3 using the settings from this thread (thanks Rob)...

For some reason the built in Carenado Bonanza was giving really bad performance.  I tried with the Carenado Malibu Mirage and the Turbine Duke at a couple of really tough airports (they were really hard on 2.2).  Framerates stayed mid 40's and up.  Smoothness was great even with wx set to Building Storms.  Now...if they could get the AA working it'd be nice.  (Downsampling, maybe?)

Well, perhaps LM should be using more beta testers who don't have a Titan.  If P3D v.2.3 is totally stutter free with a Titan (even during stormy weather), then that's great. But now the focus should be to get P3D performing well for us mortals who cannot afford a $1000 GPU. (Or they need to change their recommended spec to "Titan or better GPU".)

I have a mid tier i5 no overclock (can't remember exactly which one) with a GTX770 4 Gb and 2.3 is working wonderfully. ASN, FTX Global and Vector, A couple of A2A and Carenado planes but no really demanding planes performance wise. Cloud shadows set to the right, water detail on high with most reflections turned on, auto gen scenery complexity normal to high. Frames are smooth and locked at 30 most of the time in all sorts of cloud cover. Maybe vram is the key?

 

 

Maybe vram is the key?

 

Could be.  I'm struggling with a 3gb 780ti.  Using 4xSGSS in Inspector because without it the gauges in all my A2A planes are a shimmery mess.  But with sparse grid running in NI, stutters set in in any kind of cloud cover.  Wondering if either more VRAM or a Titan or both is the answer.  Not a happy camper as of the moment.

Even the 780ti (which i paid $740 for 6 months ago) has issues at times (at 5760x1080) coupled with a 4930k at 4.5ghz.. hitting mid teens on certain combos of addons/weather.. particularly ftx + aerosoft.. and still the microstutters even when smooth weather and lesser addons are visible (v2.3).. framerates are higher by 10 fps with version 2.2 over 2.3.. but there are improvements in smoothness that i swear is noticeable even at lower framerates with v2.3  (still not where everyone would hope though).  I dont use 4xSGSS in NI  (i've tried both with and without, in the past i had better results smoothness wise by setting NI to AA_MODE_METHOD_SUPERVCAA_64X_4v12, which i still use)

One thing I can recommend is using PROCESS explorer. I have my rig locked at 20fps for the best graphics but it was stuttering even though I was maintaining a solid 20fps.

The problem.is that like many here.i did not understand the load P3D puts on the graphics card. Using Process Explorer I found my card was running at a solid 100% and quite possibly beyond.

Moving sliders down to alleviate load in the GPU solved the issue. Now my card stays at maximum of 80% and the sim is super smooth.

In my case.. I use gpuz to check gpu loads.. i found i never go above 96% at least with p3d v2.3 (in a few tests so far).. cpu 4930k 4.5ghz.. never goes above 42% on average, spread over many cores (and i used process lasso to try to tweak this, i found the defaults to be best with v2.3, but with 2.2 and HT process lasso came in handy to find about 5 cores that yielded an 8 fps improvement, not so lucky with 2.3 so far).

Well I will say that I live with some shimmers...I'm just using the stock AA option in P3D. Guess I've adjusted my expectation slider accordingly   

@Alan_A

Have you tried a 2x SGSS? It would be more fps friendly.

 

@theskyisthelimit

SGSS is the transparency filter, so it works if activated in NI

AA_MODE_METHOD_SUPERVCAA_64X_4v12 is the AA filter mode, which should not work, do you confirm it works?

Odd I see I CPU at 100% and my GPU at about 50% I also have a770 4gb but for me it is still a stutter issue. Never seen the graphics card hit hard yet, I have parked p3d until LM addresses these issues it was meant to be about performance but there is still work to be done.

It did in version 2.2 or visually i thought it was.. ill have to do some comparisons with v2.3 to be certain though.. others on the site mentioned this mode, which is why i switched to it (in the past).

I did, but unfortunately, on my system, 4x is the minimum required to kill the gauge shimmers.

 

It's possible that, as snglecoil suggests, I need to lower my expectations.  Not reconciled to that yet, but thinking about it...
