On the other hand, trying to avoid this in Wine itself would be somewhat complicated. We mainly depend on the driver to notice that as long as you don't use non-const indices into an uniform array, it's really just a set of independent constants, of which you can eliminate the unused ones. > Since the game was working fine with this hardware in Windows (and my RV530 is > well above minimum requirements) I suspected this to be a Wine issue and I > asked at their forums, sadly with little response.

As a quick workaround you could modify Wine to use a slightly smaller array in shader_generate_glsl_declarations(), but we can't do that in general in Wine, because some applications depend on being able to use the higher indices, even if the total number of constants they use is nowhere near the limit. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
