just be bored and cruising the dregs in DX7 land came across this
So is GetBltStatus the best way? That is what I have been recomending.

P.S. This should apply to Win98 as well.

The ahem is due to the fact that you will not be able to Lock the
frontbuffer in DirectX 8.

Bash the IHVs who are doing this - there is NO need for it. All the
benchmarks are now fixed to highlight this (or at least the next release
of them will!)

<oops> I guess I sent this to the whole list rather than just an NDAd
person ;-)

So, while we're *ahem*'ing - I assume you're providing some other way of
forcing a flush? Or is there a better way atm?

(or maybe you're going to sneak up behind 3dfx/etc driver writers with a
big, pointy stick)

geForce3 is the first card that supports D3D8 pixel shading in hardware.

geForce2 does not support D3D8 pixel shading in hardware and you must use
the refrast.

is this garbage or anything interesting
