Yep! http://www.svp-team.com/wiki/Changelog

Cool Is there a changelog for 3.0.1?

The new 3.0.1 version doesn't resolve the issue. I'm working on it, wait for 3.0.2

I think that there's no issue when there're integer number of blocks in width (and height).

640*360 with 8*8 - 80*45 blocks, and it's OK.
But 640*360 with 8*8 and overlap 2*2 - 160.66*60 blocks

And I hope I know why

Well my example isn't as good as MAG's one, but if you want the testing video I use it is here.
It is just a video with some scenes from different movies and TV shows that are difficult for interpolation scripts to handle, so it is useful for tweaking scripts

The part where the SSE vs GPU difference is most obvious is from 0:44 to 0:52, and that is where the screenshots from here came from

It looks like in this case MAG's source would be more useful, though, since his example is much more obvious.

Hmm. May be it depends on the video frame size.
I've tested on 640*360.

They are still different with overlapping removed

Yes, I must confirm that the problem exists - there's a small (pixel or half-pixel ) difference in interpolated vectors (and masks) between SSE and GPU modes.
But only with overlapped blocks.

SubJunk
If you turn off overlapping, do you see any difference?

This question to Chainik.
I think yes. We will try to fix both problems.

Cool gif
Is it something that can be fixed/improved?

Thank you. You are right.
I see that results of these scripts are different.

I think there are two problems:
1) Different motion compensation phases
2) Subpixel motionblur on GPU

SSE:

Input = DSS2("filename")
Super = MSuper(Input, hpad=16, vpad=16, rfilter=4)
backward = MAnalyse(Super, blksize=16, searchparam=4, plevel=0, isb=true , badSAD=1000, overlap=4, search=3, dct=5, pelsearch=3)
forward  = MAnalyse(Super, blksize=16, searchparam=4, plevel=0, isb=false, badSAD=1000, overlap=4, search=3, dct=5, pelsearch=3)
backward = MRecalculate(Super, backward, blksize=8, searchparam=1, overlap=2, search=3, dct=5)
forward  = MRecalculate(Super, forward,  blksize=8, searchparam=1, overlap=2, search=3, dct=5)
svp_flow_lib = "C:\path\libflowsse.dll"
Finest = MFinest(Input, Super)
MSmoothFps(Input, Super, backward, forward, finest=Finest, num=48000, den=1001, algo=23, ml=0, sadml=150, sadgamma=2, block=false, blend=true)

GPU:

Input = DSS2("filename")
Super = MSuper(Input, hpad=16, vpad=16, rfilter=4)
backward = MAnalyse(Super, blksize=16, searchparam=4, plevel=0, isb=true , badSAD=1000, overlap=4, search=3, dct=5, pelsearch=3)

forward  = MRecalculate(Super, forward,  blksize=8, searchparam=1, overlap=2, search=3, dct=5)

Can you show text of this script?

Re: MFinest

null@example.com (SubJunk) — Wed, 13 Apr 2011 01:10:33 +0000

GPU vs SSE.
You see the SSE one is sharper with small details, like the trees to the right, and the truck in the lower-middle

With pel>1 MSmoothFPS does Finest-like calculations inside GPU.
