Frozen until the next 1000 frames.

OK, It should be so fast that it is more of a tiny pause than a freeze.

EDIT: You can see which cards we lose here:

http://en.wikipedia.org/wiki/CUDA#Supported_GPUs

We lose:

GeForce GT 420*, GeForce 8800 Ultra, GeForce 8800 GTX, GeForce GT 340*, GeForce GT 330*, GeForce GT 320*, GeForce 315*, GeForce 310*, GeForce 9800 GT, GeForce 9600 GT, GeForce 9400GT, Quadro FX 5600, Quadro FX 4600, Quadro Plex 2100 S4, Tesla C870, Tesla D870, Tesla S870

Too bad, so sad. :cry:
Yikes, I thought DG that you still had a 9600GT as me... I guess I have to dig-out the 520 that was glitching somehow early on and that I pulled and put-into a drawer some time ago (you had a problem too iirc), or pop for a 750Ti?

I still have the 9600GT lying in a closet, but not installed in any machine. The 520 glitches are gone with latest drivers.

The cards I run now are:

460
520
620

I hope to get a 750 Ti in not too long.

I posted about the CUDA compatibility issues at the nVida forum:

Has devtalk been responsive to you in the past? Regardless it's a good try.

I can't get too worked-up about losing 9600 support since your tool works perfectly for me as it is. But you'll clearly need to put a LOOK OUT BELOW! notice on future releases (and still it will sail past a lot of folks I suppose). ;)

I haven't posted there before. We'll see. I could try my contact at nVidia, but in previous discussions he has lamented the lack of backward compatibility for previously compiled CUBINs and I suspect there is nothing he can really do to help, so I don't like to bother him unnecessarily. The posting was intended to notify nVidia that they make serious problems for people with this new precedent (this is the first time they have removed support for an architecture). If there is a solution or it makes them think twice about it, well, that would be fantastic.

If things get really bad, I always have the option to remove the CUDA NV12 -> RGB24 conversion and replace it with a CPU version (like we had in build 2021). Then I am dependent only on CUVID and all the problems go away. The conversion is only required for display in DGIndexNV and so is noncritical. Also, modern CPUs are so fast that not much is really gained by using CUDA for it. If I pull that off, it will be possible to add back support for the obsoleted cards. I could even get fancy and do CPU conversion only on the cards that won't run the CUDA conversion.

That's hard to understand as I and others saw much more significant speed gains for M2TS.

Scratching my head as well. That's why I posted ....

Edit:
I repeated the test with a much larger file on different drives. Same result, no significant speed improvement with 2048.
I did all the tests with the 32bit binary. I'll try with 64 bit now....

Edit2:
64bit binary makes no real difference.

It seems that the speed is capped by the HD I/O :o
