At Steam Dev Days this week Valve Software started talking about their new VOGL OpenGL Debugger. Valve wrote a new OpenGL debugger that so far is appearing quite nice and comparable to APITrace. VOGL has yet to be publicly released but it's looking like it will be a very powerful tool for game developers and others dealing with OpenGL on Linux.
In ensuring this OpenGL tracer/debugger is up to scratch, Rich Geldreich has issued a call to game developers in submitting OpenGL game traces. They're concerned about seeing their full-stream tracing and state snapshot/restore code is working and will work with all of the new and greatest games.
They have already begun testing VOGL on the Steam Linux library but are hoping for some new and interesting OpenGL traces, potentially from unreleased code or for games not found on Steam. In particular they're hoping to see some advanced OpenGL 3 and OpenGL 4 usage and these traces can be recorded by APITrace on any major OS.
More information on Rich Geldreich's request can be found via his blog.
