Are you sure small pixels support 4 sample anti-aliasing? I had a
similar understanding to Brian Hill, in that a minimal multisample
feature set:
8 bits RGBA 24 bits
double buffering 24 bits
Window IDs etc 64 bits
4 multisamples RGBA 96 bits
4 multisamples 23 bit Z 92 bits
requires 300 b/p and is therefore too large for small pixels (256
b/p).
We only managed to get 3 (identical format ++at++ 60HZ) multisampled
channels with the 1024x768_60. This was also the only combination
which ircombine told us supported medium pixels.
What have I got wrong/misunderstood?
Please let me know ASAP, as we are about converge our projection
system on Tuesday for 1024x768_60 on the basis that it was the only
one to let us multisample on 3 channels.
Regards,
Mark.
