Please, note that this is "only" on your very unusual machine (it may be the same for all other Macs, but I'd count them all under unusual here in that case).

I'd love to see some performance numbers on that, by the way. Whatever benchmark(s) you like (that I can get my hands on), but the more the better.

In normal use, fVDI on a graphics card should for text drawing be about the same speed in any graphics mode as the same machine would normally (using NVDI or fVDI, that is) be in monochrome. For blitting, line drawing, etc, which is done using hardware acceleration (or at least native side code with ARAnyM SDL), a software implementation should be nowhere near the same performance (except possibly when dealing with very small lines/areas where the overhead of setting up the hardware might be larger than for software only).

My two sentences above did not originate together. I'm well aware that ImageCopy isn't compatible with VDI's other than NVDIv5.

You were saying, however, "I've seen it trying to run all sorts of things", so I'd like to hear about all these things that fVDI is supposedly failing to run.

I'm not necessarily claiming you're wrong. There may well be more than a handful of things that don't run well. But if that is the case, I obviously need to know about them or they may stay that way.

> And when such (for me) key software doesn't run, it's a big minus. It really doesn't matter if there is fancy technical reason why.

Sure. No argument from me there.

I'd like to be able to tell you that the situation regarding vr_transfer_bits will change soon, but unfortunately I won't have the time to do much about that myself. I am looking into the problem that surfaced on c.s.a.st a few days ago regarding background images in Jinnee, however. I thought that was vr_transfer_bits related, but it seems to rather be caused by vq_ctab (another NVDIv5 functions) not being fully implemented (I had forgotten about that).

> So for me CTPCI/fVDI is a minus compared to SV/NVDI.

I'm not trying to contest your opinion. Everyone is certainly entitled to one.

What you were saying about the speed of fVDI is very far from the truth, however, as can easily be demonstrated on just about any machine in the world except yours (apparently).
