ATI CATALYST 4.12 Performance Analysis
 

As far as CATALYST 4.12 goes, the big news here is probably for
those of you still playing Half-Life 2 in some shape or form, as this
driver has certainly rolled out another set of fine performance
improvements. Generally speaking, this driver set seems to be a stable
and fast one, with most applications finding some benefit
performance-wise, however small. The really big leaps can be seen for
anyone still running CATALYST 4.10 or driver sets previous to that, as
basically every test in our suite showed some big gains moving between
4.10 and 4.12.
