Single buffer + flush vs double buffer + swap
Hello everyone,

Work is ongoing well, but I'm not sure whether to go for single or double buffers for the benchmark tool.

On my C8000, with a relatively modern FireGL, if I use single buffer, the image is a bit flickery.
If I change to double buffer, it's butter-smooth.

In both cases, the frame rate is the same.

I checked the OpenGL documentation and found out that single buffers are better for older hardware, where saving memory is important.
My C8000 is the oldest computer I own, so I can't test.
I don't think any of my tests will require too much memory, though.

What would you recommend? My goal is that you could build this and run on your SGIs as well.

The whole ordeal is GLUT + C, and it builds without a line of change to the code on modern Linux and Mac, plus HP-UX 11.11, on PPC, HPPA, Intel and ARM, and I intend to keep it this way.
