Woohoo! Off to play.

Getting closer to a stable 3.2 release?

Yes indeed!
This one can be considered a release candidate.

What is the minimum nvidia requirement for this indigo version. I installed the 295.73 but I have some problems with it (very slow reaction in indigo) but not only in indigo also in blender, seem to be driver related.

this can be related to very high GPU utilization, something I experianced on my windows system too for some scenes. A GPU usage limitation or a lower priority for Indigo to keep the system usable during rendering would be a nice feature :)

Thanks for the hint zom-b but in my case it was some kind of bad driver overlapping. I cleaned my system from all video drivers and installed the newest again.

does the cpu affinity enough?

Regarding the GPU acceleration lagging the OS, to some degree this is a driver/operating system issue, because unlike CPUs, GPUs don't have preemptive multi-tasking, so if a particular work "chunk" takes long, it just can't be interrupted and the operating system can't redraw until it's done.

This is one of the major benefits of using a smaller GPU to drive the display, separate from the one used for GPU compute purposes.

On the other hand, as Zom-B suggested, we could try to counteract this behaviour a little by looking at how long the kernels run for and adjusting the work size etc, however this complicates the design and would necessarily come after 3.2 Stable!

It seems Windows 8 has it: http://www.anandtech.com/show/5630/inde ... preview/14

Oh! Now that's really some good news 8)

There will probably be a few % performance lost, but it's worth it to not have the display molested by various programs wanting to use GPU resources...

Will the 3.2 stable release be coordinated with updated exporters?

Blender just got the Bmesh overhaul, so I'm pretty sure (haven't tested yet) that exporting is borked with Blender 2.62. I'm loving the latest exporter for 2.61, it's becoming amazing, but I'm also very excited about all the new modeling improvements with Bmesh. All in due time, I guess! :)

We'll definitely co-ordinate to get all our ducks in a row for the 3.2 Stable release :)

maybe bug?

open an igm with displacement (texture)
start render
stop it
on property editor click on dispacement's image to set another "scale (b)" with up&down button
close texture editor window
try to restart
freeze

---> see render log and samples/s value when you change scale(b) value <---
