My graphics card is ATI Mobility Radeon HD and I looked a bit at their website on GPU deveopment tools. My first impression is - looks like they tools are more friendly with DirectX HLSL
I wonder how helpful it would be for me as a total beginner to install one of ATI shader debug tools(like PerfStudio)?
At this stage my main usage is going to be terrain pixel shading ,afterwards maybe some more not too complicated stuff (mostly dynamic outdoor scenes).
