Does anyone know of a test that measures frame 0 time? Or texture upload

For Smokin' Guns, I tried measuring the overall time, but an improved frame
0 time has difficulty standing out of a 2607 frame test.
I may have to create something. Suggestions for an appropriate framework?
Run an apitrace replay on a trace trimmed to frame <whenever the
textures are first used>? Sure, apitrace isn't real-world benchmarking
for fps, but it should get at the "how much did we cut off of load
time", assuming that texture load time isn't swamped by apitrace
decompression.
I believe Frank has a microbenchmark for measuring texture
upload time. Maybe he can share it with us. But, data obtained from real
apps is always preferred.
