First I thought it’s a Fuse bug with AMD cards, there is also a bug report for Fuse, but it seems to be an issue with Stride itself because the vvvv gamma examples also have problems.
Nvidia:
versus
AMD Radeon 6500M
Cannot edit my post? weird..
anyway:
on closer inspection it seems to be an unrelated issue to the Fuse Particle-bug.
The output buffer of ComputeBuffer in Fuse left all Elements except the first one without data, the bufferData in the Stride-Particle examples exists, though.
Just thought I should add this to not cause confusion.
Yes, Radeon cards seem to have issues with geometry shaders, unfortunately. Not much we can do… If you find a gemotry shader that works, please let us know, maybe we can build up from there.
You may need to use normal instancing and lower counts. See the instancing help patches.
