I have been trying the Deferred rendering pipeline with both the latest SL release and SL releases that have the latest alpha / beta of the Shadow Draft technology in them with my ATI Radeon X1300/X1550 Series video card / Catalyst Control Center, official drivers. However, the Deferred rendering pipeline does not seem to work with it which, given the fact my video card is pretty recent and has most modern shader technologies that most video cards these days have and is up to date with all drivers I consider a viewer bug. Whenever I open the small Debug Settings window and try enable RenderDeferred (while having RenderUseFBO also set to TRUE) I experience a different issue which each version of the viewer:
- With the latest official SL viewer or First Look / Release Candidate viewer where the Shadow Draft technology was not yet included, enabling RenderDeferred causes the rendering to become like the one posted in the screenshots below. Basically, every alpha texture stops rendering, terrain and sky stop rendering, and solid prims render in some bright rainbow color that changes depending on the angle you look from.
- On clients which do include the experimental Shadow Draft system, attempting to enable RenderDeferred causes the client to freeze for a second then the setting jumps back to false. At first RenderDeferred will look as it sticked to true, but if you deselect the Debug Settings window you'll see it switching back to false and refusing to apply.
I'm marking this as major given the fact it's probably going to hit First Look in the next few months and compatibility with all recent graphics cards is I believe a priority. If any other questions or info is needed feel free to ask as I check these entries often.
