Fastest running CyberStorm Mk III?

[matthey]

if here are users with overclocked 68k cards, i like to see how fast then SDL games at 640*480* 16 bit resolution can run.

I upload a defendguin with framerate display

it work on default in window.but for fastest speed it should start from shell with the defendguin -f

this work in fullscreen

Here is the link for download, can copy to ram and run.note music should stay off

I got 20fps most of the time. It flashed a higher or lower fps from time to time but it wasn't displayed long enough to read it. I had AWeb & Genesis going in the background and my memory was probably pretty well fragmented. I decompressed to ram and did a lot of compiles and disassembles first. The speed seamed fast and responsive but the gfx were messed up. The foreground objects were multi-colored. The background was fine.

err what is the speed of your processor(s) and what card do you have this would help if we are doing benchmark.

do you own a apollo @90Mhz?

i did the test with sound 8 FPS most of the time,but when everthing went mutunt it jumped to around 20 - 24 FPS..no problems with GFX.

Nope. Just a CSMK3 with 68060@75MHz, 50ns SIMMs running with the fastest memory settings of the CS, Mediator 3000T/4000T with Voodoo4 and AmigaOS 3.9 with updates in a 3000T.

WOW WOW WOW thats fast.

lets see if i can get anywhere near it.

the last test was a trick (8 FPS) it's real but it was done on my Blizzard PPC TEST CARD which has a 200Mhz PPC processor overclocked to 240Mhz with 060 clocked @50Mhz with the slowest memory setting.

will upload test to this thread soon from one of my faster cards.

20fps look great, but i dont understand wy colors are wrong.

Can you post the sashimi output, also delshay can do it.

here is a test Program that show what Pixelmode your GFX Card support.If your GFX Card support RGB16 Pixelmode then speed is fastest.

@bernd
The Voodoo4 supports most every gfx mode but the big endian modes have problems with the colors of some objects. This is an Elbox bug for a long time and they don't seem too enthusiastic about fixing. Having big endian and small endian modes open at the same time can cause gfx corruption according to Elbox. Elbox recommends using little endian modes. Did your demo open in big endian mode? That would explain why it ran so fast too.

i will upload test on monday. note my Bvision is overclocked from the standard 83Mhz to 100Mhz i don't know how much of a effect (if any) it will have on the test result.

netsurf do the same, it run fast when you have a RBG16 Pixelmode.does netsurf too show wrong colors ?

the Problem when use RGB16 PC Pixelmode is that SDL do not work ok.
the convert is done by a shift and mask value.(i explain at utiltiybase more)

When use RGB16PC then there need 2 bits from upper rotate, so that they are in the lower 2 bits.

But because C do not rotate the bits in the upper come not to the Bit Position 0 and 1 and so color information get lost.
 
So cant use RGB16PC mode in SDL good.I thought the classic amiga all use RGB16 and only winuae use RGB16PC.So i thought it make no speedloss.

SDL amiga do the way same as MOS, it use a RGB16 Mode intern and swap the data.

for others with RGB16 PC screenmode its maybe faster when set the env variable SDL_SWSURFACE

maybe delshay can try out if it work faster on his Card

[delshay]

i wiil try on my card when i have time,as at the moment i have my test card plug-in testing out new modifcations,which may make my card faster.

i can also say the latest test shows the Blizzard PPC card will not go 100Mhz (to be comfirmed)

[zipper]

I remember my CSPPC began to corrupt with 97 MHz.

[delshay]

on my fastest card im getting around 12 FPS @72Mhz and 15 FPS @74MHZ in normal gameplay but speeds up when everything go's mutant.

68K processor is limited until it can be clocked on it's own.

[unusedunused]

I send Matthey a Version that work on his system with rgb16PC and 20 fps with correct colors now.

maybe this run on your system too faster ?
Note, the framerate is limit in program code to 25 fps.More is not possible.

Problem of this version is, red color accuracy is not soo good, but it look still nice.

[Evillord68]

I have two CSPPCs, both are running with 80MHZ. I never tried more.
A friend at http://www.a1k.org (Reptile) has a running CSPPC with 85MHZ.

I thought mine at 66.7Mhz was fast...*sniff*...

How do you get 80MHz? You need special revision/mask 060?

[68KAmiga]

You need good Ram`s (50ns) and a MC68060 Rev.7 CPU.

This CPU can clocked (theoretical) up to 100MHZ with active Cooling.

The MC`s are better than the XC`s because they stay more cool as the XC.
