Issues of Boudery Artifacts while using Pyro Cluster Sept. 28, 2012, 11:04 p.m.

Hi There, I want to know if there is a solution to this problem. I get seams or artifacts at the Borders of the container when I try to do Pyro Clustering. To explain my problem more clearly I have attached 2 images below. I posted this question on other forums but was not able to get a lot of feedback on this.Hope I get some answer here.

amd driver crashes when using opencl acceleration for pyrofx Sept. 28, 2012, 4:30 p.m.

I believe it should be possible to do OpenCL on the 7970 while using the FirePro to handle display, though I've never tried it (assuming the driver is fixed for the 7970, of course).

So it means there is no need for a Crossfirex connections between the two graphic cards to use second device as a OpenCL device. Thanks a lot once again.

AMD Radeon 7000 series or FirePro W cards, because of the current driver, will crash regardless of the size of the sim or VRAM on the hardware. This is a driver bug.

The 5900 should work, but you may run into VRAM limitations with its 2GB framebuffer. Generally voxel sims > 250x250x250 may run into trouble with 2GB.

Thanks a lot that was really helpful. I just want to know one last thing which is not probably directly related to my question but it seems important.
Assuming that I already have a Amd Firepro V5900 which has 2GB VRAM. Is it possible to couple it up with a Sapphire Toxic Radeon HD 7970 which has 6GB VRAM and use that solely as a Opencl device by setting the enviorment variable to second device even when these two devices cannot take advantage of Crossfirex Technology.
