Yeah, what a great definition, except it's hardly "native", since the VI knows nothing about any of (theoretically countless) RDP's frame buffers. The VI can copy pixels from any address in the RDRAM...

You know very well I didn't say that, fatpimp. I said that the amount of pixels copied from the RDRAM on each VI line had nothing to do with VI_WIDTH_REG. VI_WIDTH_REG, however, is an offset or delta...

You obviously failed to read my quote from DirectX 8 SDK help files. I'll repost it once again just for you: "RECT structures are defined so that the right and bottom members are exclusive—therefore,...

Nothing like that. First, you cannot represent this with memcpy(), because the VI does interpolation on every pixel. To simplify what's happening, for each VI line, the VI copies an amount of pixels,...

It's not a width of the VI, it's an offset in RDRAM bytes between successive lines that the VI fetches from the RDRAM and then draws.

No, Dr. Cat, it does not intrigue me in the least, because the title screen shows in 1964 0.8.4/0.8.5, so not showing it in PJ64 1.6 is most likely an accuracy improvement, because my plugin...

I don't care if it was better or worse with one CPU core or another, because it has nothing to do with the RDP and it has everything to do with the CPU. Another game that has bad geometry presumably...

The broken geometry is a core/CPU emulation bug, as was already discussed in z64gl thread at emutalk. The game only renders correct geometry in 1964 v0.8.4 / v0.8.5. The same applies to Battle for...

It was my mistake, what I meant was ((var >> 6) & ~3). ((var >> 8) << 2) is not equivalent to (var >> 6), like you sort of suggested in post #193, it's equivalent to ((var >> 6) & ~3).

Ah, you're partially correct, for some reason I shift a 16-bit unsigned value in some texel fetching functions and 32-bit unsigned value in others. I'll see if I have an inclination to change this to...

As I said, AH accesses are not faster than SHR on Pentium 4. Secondly, there's nothing preventing an abstract compiler to be smart enough to use AH accesses, if I right-shift an unsigned 16-bit value...

Maybe, I don't recommend to trust anything without experimenting with a profiler. Last I heard, generally 32-bit memory accesses and arithmetic were faster than 16-bit on x86-32. If you want to avoid...

The Pentium 4 Optimization Manual tells that I should avoid the use of AH, etc., because it involves an internal shift micro-op, so these two code sequences should be almost equal on what I have.
