FFTF - blurries at altitude

[GentleGroove 69]

Hi everyone

I'm using P3D 4.5 and just started using FFTF. I'm very happy with the performance - on ground, departure and arrival, performance is just great and I have no stuttering at all.

However, occasionaly I am getting blurries at altiduon the descent phase of the flight, slightly after TOD, which is puzzling me. Since at this point the FFTF value is actually higher, why is this happening? This happens both in AGL and FPS modes.

If anyone has any suggestions, I'd be most grateful.

Cheers

theres a CFG tweak for that , search rob ainscough, by the way your addons and settings would help ?

Hi maybe my first post was not too clear. What I meant to say is that I'm using the FFTF Dynamic addon. While it works flawlessly close to the ground, I'm seeing blurries from altitude while descending (at FL200 and above) which doesn't make sense to me, since according to my settings FFTF can go up to 0.33 above 4000 feet.

CPU and speed?  HT On or off?  Location?  Add-ons?

Hard to even guess with so little info.  In general, blurries occur when the CPU isn't keeping up with the scenery loading.  With FFTF set to 0.33 above 4000 ft, then you should see the same behavior with FFTF disabled, as 0.33 is the default value.

I saw blurries (and other side effects) until I switched off Dynamic Texture Streaming. Worth a try if you have it switched on.

I'm gonna guess that FFTF isn't this:
The Fast Flux Test Facility (FFTF) is a 400 MW thermal, liquid sodium cooled, nuclear test reactor owned by the U.S. Department of Energy.

Hi

AMD Ryzen 2700X @ 4.00 Ghz, GTX 1070, 16 GB RAM, HT is on and no overclocking.

Besides FFTF, the only external changes I'm using are RTSS to lock frames @ 30fps and "prefer maximum performance" on the NVIDIA Control Panel.

Currently using the PMDG NGXu, REX Sky Force, Active Sky, ORBX Global BASE and Vector.

The blurries don't seem tied to a particular area or addon though, and sometimes they will happen in areas with little content (desert / forest areas / islands and ocean, etc).

What's the logic behind the AffinityMask set to 1020 (binary 0000001111111100)?  That still shares the core running the main thread with another logical processor, and it only allows P3D to run on 4 of the 8 cores.   That might be a big part of the problem--first, the main thread should have a physical core dedicated to it, and second, why in the world would you want to prevent P3D from using half of the CPU's cores??!  Something like AM=65493 (binary 1111111111010101) makes more sense to me.  That puts the P3D main thread on a single LP on core 0, and blocks SMT across the first three cores where you don't want the main/scheduling threads  competing with other threads running on a paired SMT LP.

I suspect this accounts for a significant part of your performance (=blurry) issue.

[Afterburner 374]

Yes, I also suspect that the AF setting is responsible for the blurries that you see at high altitude. Also, I advise not to use external FPS limiters in combination with FFTF; that program works best with the internal FPS limiter.

Strange. I was frequently told to keep away of the internal limiter as it would carry performance penalty when used.

Im actually am looking for a way to limit my frame around 30 but the limiter which comes with the Amd drivers seems to cause stuttering.

[Afterburner 374]

Yes, there is a performance penalty if you leave the FFTF value at default. However, the program FFTF Dynamic adjusts that value with height, so that the performance penalty is eliminated at low altitudes (if the minimum value is set to 0.01), while at higher altitudes, that penalty doesn't affect the FPS so much due to the much higher overhead.

Thanks. I did some testing with Process Lasso, and 1020 was the most fluid option. Although I have to say, I was pretty surprised by this number too, and now that you mention it, I don't think I had this issue before that.

I will try with a more tested and tried AM and see if the problem still stands.

Cheers
