Is something broken, or have BETA started to send VLAR's to CUDA Nvidia cards now?

I've got a whole load of them on my new GTP980, both CUDA42 and 50.

Edit: I'll abort them, they run soo slooooow :-)

IIRC that change was made a while back, possibly after we got x41zc.
Basically testing how well fast cards cope with VLAR now.

yes, they are slow, but GPUs no longer choke on them.

I don't think we did a full review on the user experience and the general performance and I don;t think it was something recommended for main.

But with one thing and another that testing may well have been lost from the collective agenda.

One of the others might remember details.

Hmm, I thought they reversed that test, and stopped vlars again from Nvidia cards.

Ah well, I'm sure someone will remember, because I sure don't :-)

IIRC, the test was specifically when the newer Kepler architecture cards were released, to find out if the CUDA application was any more successful at VLAR than it had been on older cards. It wasn't, so the change wasn't duplicated across to the main project. I don't think you'll get VLARs unless you have one of those recent cards installed.

Ah, Ok. Well the GTX980 is one of "those recent cards", so I guess that answers the question.

I'll let them run, if I get a new batch.

Plus, we need that setting to test the new apps in the first place.
Benches only tell you so much.

ah. cc 3.0+ Don't need to press Eve into service then.

@Richard Thanks for digging that out.
