Sorry for anothe one, but mabye this time it looks better :)
Another problem with my CT63 is that its soooooo slow.
For example silkcut or ocean machine demos run around 2 max 4 frames per second :(((((
When i do run nembench test i get much worse results than Radolphe gives on
his web page for 060 at 66 MHz:
http://www.czuba-tech.com/CT60/english/benchs_eng.htm
for example:
Radolphe Me

Linear (stalled) integer 66.601 Mips 836 % 16.61Mips 208%

Linear 32bit write 67.389 MB/s 1044 % 24.45MB/s 379%
Linear 32bit copy 27.025 MB/s 837 % 9,9MB/s 306%
But when I run zBench and do CPU testing I almost get the same results than XI :
http://satantronic.atari.sk/CT60/CT60_zBench2.gif
I don't know mabye I'm doing anything wrong, or mabye its something wrong with my hardware.
My config:
F030 + CT60 at 66MHz ( changing to 85 MHz makes all benches go higher but silkcut runs the same )
ST-RAM: 16MB
FAST-RAM: 256MB Infineon 133 MHz 2 CL
Could anybody have some ideas ? I want to see silkcut in real, not just on youtube :)
Thanks.
