I know this post is 2 years old but I'm still experiencing this issue with X-Plane 9.62 and ATI Mobility Radeon HD4670 1GB. Has this been addressed? More info here (will post screenshots this evening):

Thanks.

The work of variation is changed…in v8 it meant more layers, more overdraw, more vertices. In v9, it means more complex shaders.

So on a system with plenty of unused shader power, this change in resource use will mean more fps.

On a machine with plenty of bus bandwidth and fill rate, but not much shader power, this would not mean a fps improvement.

Generally speaking, for most cases, this is a win though…shader power is much more available than “ROP” (raster operation” fill-rate, at least for the relatively simple shaders we use.

You wrote : “This means less information in the DSF (which means smaller DSFs, faster loading and less RAM use), but it also means variation is only visible to those with shaders.”

Shouldn’t it mean it would improve the fps when shaders are on?
