As mentioned in a previous panicked yell in the shoutbox,
vs3 and ps3 shaders dont draw on my new ATI 6770 graphics card.
Any idea of a reason for this?
simple test is clone Constant.fx, connect to grid and renderer
see a white quad
change the technique to vs_3_0 or ps_3_0
see the quad disappear
Is this the old incompatibility with ATI re-emerging? (i.e. an oversight in the recent implementation of ATI friendly shaders)
It’s likely something that can be smoothed out, and I’m certain that the hardware is capable.
Likely of importance is that i’m running on beta26 with the new choice of shader compiler.
Can’t test the machine with <26 now as it’s in the middle of an install.
p.s. feel free to change thread type from question to bug if we can identify that it’s something to be fixed within vvvv .
You clearly point out that it is possible to write a shader that will run on NVidia but will not run on ATI.
Obviously we need some more clarification with this, preferably with not only empirical results, but a definition of what is supported differently on the 2 manufacturers’ platforms.
I will test on beta25 and report if results differ from previous negative results on 26/6770/vs,ps3
dunno if it is of any help, but a few days ago while patching with @Lasal on ATI 6950 we ve foud out that some shader may or may not work if some render pass is on dda 0 while final renderer is in dda 1. I haven t got a clear explanation but things worked out at the end.
Have you tried to just launch the shader out of the patch context with a minimum setup as possible?
I am using a lot of VS3/PS3 shaders now wit the ATI and all works fine, even the GPU particles.
