fft3dGPU 0.8.2

[G_M_C]

From this thread: SEt's Avisynth 2.5.8 MT compiled for *X86_64*, Latest Build 4/16/2010

I found that there is a 64 bit verion available of fft3dgpu. But it is also mentioned that (quote)

note:The hlsl (shader program) file is edited from the original to adhere to pixel shader 3.0 syntax rules.

I've take this PS3.0 HSL file, and i have been using it with fft3Dgpu version 0.82 (i installed 0.82, and copied the "new" hsl file over the original one). It seems to work, and i have the idea that it is much faster than the original HSL. At least on my HD5770.

Can someone confirm you can simply "update" the HSL on the original 32-bit fft3dgpu, without errors or problems ?

Wow!! thanks G_M_C, I will test it on 32-bit fft3dgpu tomorow
if it's usable, it's help me alot of encode time.

[Hiritsuki]

To G_M_C
it's can be used on 32-bit fft3dgpu
but I don't know it's faster or slower than original hlsl.

I've tested and you are right;

AviSynth test file

DirectShowSource("ïnput_1080p.grf",fps=23.976,audio=false) \ (grf opens blu-ray m2ts with CoreAVC2.0, output YV12)

fft3dgpu(precision=2,plane=???,bw=32,bh=32,ow=16,oh=16)

AssumeFPS (24000,1001)

Plane=4
HSL2.0 12.8~12.9 fps
HSL3.0 13.0~13.1 fps

Plane 1 & 3
HSL2.0 and HSL3.0 scored almost equal; 23.8 fps

This on my machine;
QX9650 @ non-OC 9x333 for fair comparison with other users
Ati HD5770 @ non-OC
XP 32-SP3

Could you please run a comparison against FFT3DFilter with same settings?

Wow! I also test it, but I use no Plane to run it.
My video frame size is 1920*1080.

fft3dgpu() # used original to run

HSL2.0 15.7~16.4fps
HSL3.0 16.1~16.6fps

This on my PC
i7-980X @ oc 200*21
nVidia GTX275 @ oc 800-1680-1200
Win7 64bit (use with 32-bit avisynth)

fft3dgpu(), default uses plane=1 afaik

@Boulder, i'll set it up.

[Hiritsuki]

Tomorow I will use new graphic card to run this test.
Is the MSI N465GTX TwinFrozer Gold Edtion (can update bios to GTX470).
Think that will more difference with HSL2.0 to HSL3.0.

[Hiritsuki]

I had try GTX465 to run this and find a result is HSL2.0 or 3.0 is can't run more than more faster in new Graphic Card than this FFT3DGPU devlop time.
Old Graphic Card that like 6600GT or 7600GT is the FFT3DGPU devlop time.
If HSL 4.0 or 5.0 or framework for renovation maybe run more than more faster.

New test below

My video frame size is 1920*1080.

fft3dgpu() # used original to run

HSL2.0 16.1~16.4fps
HSL3.0 16.5~16.7fps

This on my PC
i7-980X @ oc 200*21
nVidia GTX465 @ oc 800-1680-1000

Anyone used NVperf?
Who can tell me what this effect is?

[Chabb]

Could somebody help with such bug in fft3dgpu?

It started since I've changed 8800GT to GTX460
All other things remains the same:
OS (WinXP SP3), video driver (258.96), fft3dgpu and avisynth (2.5.8) versions
It occurs not every time, mainly with HD sources.
Sometimes reboot helps.
Is it driver issue or something else?

[Sharktooth]

probably a driver issue

[Beak]

This is probably a dumb question but I am curious.

I have a Radeon 5770, Core clock is 860Mhz and the memory 1200Mhz.
I have a i720 quad core O/c to 3.6.

I can run fft3dfilter in any MT mode I can think of and still get no more than 9 frames per second on HD encodes ie 1280P.

With fft3dgpu I get up to 18fps with the same settings.

FFT3dGPU(sigma=2.0, bt=4, bw=32, bh=32, ow=16, oh=16)
MT("""LSFmod(smode=5)""", threads=4, overlap=8)

How is this possible? Not complaining, just curious.

The key word is "encode".

Ok, are you actually testing the speed of an encode, or are you simply testing the speed of the avs script.

If you are encoding it, it should be pretty obvious. Because fft3dfilter needs to share the CPU with x264 (slowing both down), while fft3dGPU does not (so x264 gets pretty much all the CPU). This is the main reason why people use fft3dgpu at all.

Of course. But it is still only 1 thread on an 860 Mhz processor. Is there a different math language used by a GPU?

If just playing the script without GPU I cannot reach same speeds with 8 virtual cores at 3.6 gig.

1 thread? Try 500 threads. You shouldn't even be comparing thead counts when talking about CPU vs GPU. They are so different it's meaningless.

And ofcourse CPU (x264) +GPU (fft3dGPU) will be faster than CPU alone (x264 + fft3dfilter). That makes sense, no? (Only way that wouldn't work is if you have a GPU bottleneck, which isn't the case here).

Try testing fft3dfilter vs fft3dGPU WITHOUT any encoding. That is, just the script, no x264/xvid/whatever.

[woah!]

i get this now, upgraded from a 260gtx to a 460gtx.

seems the betas nvidia drivers dont fix this either... works after a reboot can open script many times in a row with no issue. then i open videoredo and edit a mpeg2 hd source and save. now without doing anythind more, open avs script and get the same as the pics show above?

weird stuff...

[Beak]

Can anyone comment on whether there would be any visible difference between precision=0 vs precision 2 with this filter?

I can see nothing but my TV is not really the best.

Is this available somewhere other than mediafire? I am unable to download from them and it'll be a cold day in hell before I disable the popup blocker on that place. I made that mistake ONCE. You have to task kill your browser to get it back from those assklowns.

You should configure the blocker to block only popups. Not the whole Internet! (I've no proplems to DL from MediaFire, and there's not one single popup ...)

Here it is on MultiUpload. Hope you can DL from one of 'em without having to reinstall the OS.
