Maybe you have a slow hard drive and it is masking the code improvements.

How big is the file that took 56 seconds and what is the video type?

My PC does a 4.2GB AVC M2TS in 18 seconds. So I guess your disk IO is seriously deficient. You may want to look into that.

Exactly. Benchmark testing with my conventional HD indicates 70.....80 MB/s read or write transfer rates.
So this seems to be the bottleneck in my case.
Anyway, I am happy that v2048 works with my GeForce 9600 GS.

I have a fast spinning mechanical drive with a very large cache interfaced with SATA 600 (not an SSD). HDTune gives me a read benchmark of 190 MB/s.

That's about 2.5 times of what I am getting with my HD. It is clear now why I am not getting more speed gain with v2048. But as long as it works with my system, I am fine.

I never announced the changes for 2048, so here they are. Note that the last two were slipstreamed
today, so if you want them, please re-download and update DGIndexNV and DGDecodeNV.

* Greatly improved the indexing speed (almost twice as fast for transport streams).
Note that you need relatively fast disk I/O to see these improvements. CPU optimizations
can be swamped by slow I/O.

* Updated to CUDA version 6.5 and built with VS2013 Express (Update 3 RC). Note that CUDA architecture
sm_10 support was dropped by nVidia. That means really old slow cards are no longer
supported.

* Made fixes so that alternate languages set via the system locale setting are now properly
handled. This is a "poor man's" substitute for full Unicode support. Full Unicode support
is not possible because it is not supported by Avisynth.

The "really old slow" part describes me pretty well! :twisted: :D

I suspect your readme is done already but for next time you might want to add some more clues as to what this means 'zackly i.e. I recall that I looked-up my 9600GT (which she's a no work) but don't remember the conditions i.e. what sm_10 translates to in the world of non-techies.

But maybe anudder cuppa coffee and I'll recall... :scratch:

Good morning, laserfan. Search for sm_10 in that "Search this topic..." box at the top and you will find everything you need to know.

I've added the relevant link to the readme. Thanks for the suggestion.
