Uplink Demo slow on G3

Not necessarily. I can run ghost recon with no problems at 1152*768, yet Uplink does still become sluggish on my computer at times.

Uplink runs perfectly on my 500MHz G3 Mini-Tower with a Radeon Mac Edition (32MB DDR memory) on OS 9.1 I didn't check to see how much memory was allocated to it, though.

At first I thought that the slowness was caused by application processes running in the background. But when I quit my other applications Uplink still ran slowly in Mac OS X.

When I tried Uplink in OS 9, it was a little bit faster but still felt sluggish.

I suppose that my problem with slowness is caused by my slow CPU and antiquated ATi Graphics "Accelerator".

Thanks for the suggestion,

Thats my point. A game that (should) utilize OpenGL more than Uplink runs fine, but Uplink does not. Incedentally, I'm 300Mhz and a couple graphics card revision below the requirement to play UT2K3, yet I can get 30-40 frames per second.
I think the problem lies with Uplink, not my computer.

------------------

I have tried the Uplink Demo (v 1.3.1) on three Macs of mine:
No other apps except or the Finder are running. Most sharing services are off. Game settings are the default ones. Sound is on.

PowerBook G3 Wallstreet G3/233, 384MB RAM, Mac OS X 10.2.6. 4MB RagePro LT
The game starts but is not even able to display the splash screen. No way to see any graphics, the screen stays dark. Music and Sound FX tell me that the app is running. I have tried with external screens as well, no luck. I can blindly quit the game using command-q at least.

Beige PowerMac G3/292, 384MB RAM, 10.2.6.; 6MB VRAM ATI Mach64 standard onboard graphics
This machine is able to display the game. Though it is SLOW as hell. Even unaccelerated Aqua is a LOT less glacial! You need to wait 3/10th of a second for any button to highlight and then wait until the tool tip text has run in. If you click the button before the text ahs completed the button doesn't work. (no bail out possible) So you need to blur and refocus the button again, wait for the text and then click. takes about 2 seconds for each button to click.

Same G3 as above only running Mac OS 9.2.2 using OpenGL 1.2.1 drivers.
Game performance is even worse. At least half a second for a button highlight. The OpenGL implementation in Mac OS X is noticeably faster.

iMac G3/233, Rev. B, 256MB RAM, ATI Rage II Pro with 6MB VRAM, Mac OS X 10.2.6
The game is MUCH faster, though still sluggish. When it comes to the local gateway selection the game seems to hang or wait or missing to display a button. After some trial I can dismiss the world map dialog and the game progresses. Unlike with the beige G3 I only sometimes experience the problem with having to wait for the graphics to click a button.

I can add a G4/450DUAL with Rage Pro 128 and 800MB+ RAM to that setup when I get to work on monday.

Resumée:
These three machines are very close together when it comes to processing power. The only big difference is the graphics processor. All machines have been tested in 640x480 mode and the beige one up to 1280x1024. Both 16bit and 32bit color depth setting tried with 32bit settings beeing even slower. Increasing the resolution did not change a lot. 4MB VRAM sadly is just not enough for this game. Anything from 6MB upwards can be used to at least display graphics though performance is terrible. Sound is interresting and non-annoyingly playing well on all of these Macs.

I just don't understand why such a game makes so intense use of OpenGL. Maybe someone in the know could explain to me why Uplink needs OpenGL that much! A way to reduce the blending and effects to make this game run on older hardware would be realy great.

The demo runs great on my Beige G3/233, upgraded to G4/500 with a radeon 7000 mac edition. If OpenGL is enabled, the game runs smooth, slowing down only a little in the world map. Those of you who have the Radeon Mac Edition, I would suggest upgrading to the 7000 mac edition. It's by far the best PCI graphics card available.

-Biggie!

anyway, uplink isn't brilliantly coded... there are a lot of memory leaks etc (for the PC version anyway). I dont know if the people at Ambrosia sorted any of this out or not. The major problem was the enlarged world map. With more then say 20 computers on it, and links all over the place, its slow as anything

We dont stop playing cos we get old.

I run the following things:

Grey Box Power Macintosh G3 233mHz

(I have no idea what my graphics card is)
Just one monitor and no other applications running
An incomplete pirate version of 9.1 (Dont scold me it was from a friend with a bad burner)
Ram: 96 VM: 156
Uplink is slightly sluggish when pressing buttons which has numerously led to me lose fatal missions and rupture my user. DAMN IT!
