For example, PS:326, PS:428, and VS:428 IDs correspond to different shaders.
For example, in the screenshot below, PS:697 is used by ergs 21, 23, 25, 27, 29, and 32. If you add up the shader times for PS:697, these 6 ergs take 77.6 microseconds in the GPU.
column shows the percent of the total GPU time used by all selected ergs. For example, PS:697 takes 77.6 microseconds, which is 40.8% of the total GPU time for ergs 21, 23, 25, 27, 29, and 32.
drop-down list you can select which code to view -
code, which is available only if the game supplies the high-level shading language at run time, or the
code, which shows disassembled intermediate shader language. Assembly code is always available.
You can apply the saved settings to the required shader any number of times, without opening the
dialog box. For example, you specify some settings for VS:1, then go to PS:3 and set different settings. Later if you want to switch back to VS:1, the settings specified for VS:1 will be saved.
