Windows vs Mac Runtime

[GMG Mike]

My discoveries with benchmarks Mac vs Windows SC Runtime:

Windows is faster at graphics, but Mac is faster at scripting.

Windows
Optimized Sprites: 4-5 ticks
Speed Test: 3-4 ticks

Mac
Optimized Sprites: ~9 ticks
Speed Test: 1 ticks

Mac tests on a Mac Pro. Windows tests were in VMWare on the same Mac Pro. Windows XP was used for the tests.

Space CPU Usage
Mac: 41%
Windows: Less than 1%

Space CPU usage I just can't figure out at all. What the hell is wrong with RB graphics on the Mac???

thats so interesting, mac and windows have opposite results

[WarHampster]

Weird... I did notice that SC3D ran way faster on my PC, although at the time I attributed it to my mac being slow.

Perhaps it's the carbon framework.

I just converted the space game to cocoa to compare cpu and came across these results:


Here's the download if you want to try it for yourself:
Cocoa-ified Space - 10.5+

Though I only used basic cocoa drawing for the job. Plus the game is running and updating the screen 60fps. I bet OpenGl would be 1% or less.

P.S. Click in the window and you enter hyperspace. Keep clicking and soon you're well past the speed of light.
P.S.S. Yay for big pictures.

Bollocks. Quartz is Quartz, whether it's Carbon or Cocoa.

[Gan]

Bollocks

Heh, yeah you're probably right.

Though sometimes I wonder. Some carbon games like Oberin and Yipe run incredibly slow on newer macs when they would run speedy on older macs.

[WarHampster]

Probably because they're running on Rosetta.

[Gan]

Hmm. Does Sc run on Rosetta?

[GMG Mike]

Hmm. Does Sc run on Rosetta?

No... Don't you remember the huge switch from RB 5.5.5 to RB 2009r4 that temporarily gave me diabetes?

[Gan]

Oh yeah. Heheh.

Is there a difference in RAM usage.

If there isn't much of a difference, I am guessing its the way windows does their hyper-threading, thus rendering the %usage inaccurate.

[Connors]

Don't programs in general tend to run slower if you use an emulator?

[GMG Mike]

That might explain the speed test. But the graphics are so much faster, even in the emulator. If I were to boot native XP (with the ATI Drivers) it would be even faster.

I didn't note a difference in memory usage. All of the sprites, etc. are loaded into memory uncompressed ready for drawing.

I don't think VMWare passes through any hyper threading etc. It was only set for 1 CPU I think. Also, the runtime is not inherently threaded.
