1) Rapture

Still trying to figure out the memory timings, slight improvement, hit 59.1 FPS in Quake2@640x480.

Tried compiling flops with altivec turned on, don't know whether this is making a difference or not. Compiler options used were -warpup -O2 -mmultiple -mcpu=7400 -mabi=altivec -faltivec

If anyone wants to try this on some other WarpOS platform here is the executable. I don't testify that these results are indicative of anything other than running the same executable on the machines above.

Just ran AFlopsWOS on both and it is faster on both machines, so Altivec compiler flags aren't doing anything.

@grelbfarlk:

For a bit of a laugh, I ran flops on a 604e 166MHz (well, it seemed fast at the time ). Here's the results:

How does the Altivec flag work anyway? You can always compile with -S and see if there is Altivec code in it.

This page has a little information.
https://gcc.gnu.org/onlinedocs/gcc/R...C-Options.html

Without Altivec code in the source it seems to not do anything. Should probably move this to a coders thread.

According to the changes note included with build 295 of the Sonnet archive it seems to be the "Force Computers Arroyo PMC card" I don't see any of those on Ebay though

Don't worry nothing is exposed, spent past two days on eBay looking for the thing!
No luck so far...

That's Awesome but isn't price and availability still a problem like with the Sonnet card?
