Ok, finally had a bit of spare time to collect some performance figures for the Revision C, 1.33GHz 12" PowerBook, running Battlefield 1942. Specifications of my PowerBook are the standard-issue 1.33GHz G4, 64MB nVidia GeForce FX 5200 Go and 60GB HDD. I have 768MB RAM. Mac OS X version is 10.3.4, and all the latest patches are applied. Battlefield 1942 is exactly as installed from the DVD-ROM. I am running off AC power, with processor performance set to 'Highest'. No other software except the Finder was running during the benchmark tests. Connectivity to internet game servers is via the AirPort Extreme card, communicating with my 802.11b base station (about 50cm away, so full signal strength), hooked up to a 512kbps ADSL connection. For Battlefield 1942 configuration, default settings were used for all bot configuration in single player mode, ie: 100% bot count, bot AI set at 20% CPU time, and 'Medium' difficulty. Sound configuration was as per defaults. Graphics options were adjusted by selecting the 'Low', 'Medium' or 'High' presets in the Video Options panel. Resolution was adjusted in the same panel. Benchmark frames per second scores were determined via manual assessment and averaging of the onscreen FPS counter (invoked with 'fps 1' from the BF1942 console) whilst performing several actions, including running around, shooting at enemy soldiers, entering bunkers, changing weapons, and entering and driving vehicles. Due to the highly manual procedure involved, your mileage may vary...severely...and I take no responsibility for any harm or damage these benchmarks may cause to you, your system, or friends and family. Single Player Mode, 'Operation Battleaxe' map: -1024x768x32, high graphics details: ~ 12 fps -800x600x32, high graphics details: ~ 14 fps -1024x768x32, medium graphics details: ~ 13-14 fps -800x600x32, medium graphics details: ~15-16 fps -1024x768x32, low graphics details: ~ 15-18 fps -800x600x32, low graphics details: ~ 18-20 fps Multiplayer mode, 'Omaha Beach' map. Server ping approximately 110ms. Very lightly loaded server, 2-3 players online. -1024x768x32, high graphics detail: 8-10 fps -800x600x32, high graphics detail: 10-14 fps -1024x768x32, medium graphics detail: 8-10 fps -800x600x32, medium graphics detail: 13-14 fps -1024x768x32, low graphics detail: ~15 fps -800x600x32, low graphics detail: ~21 fps. A few points. The game looks great at both the 'high' and 'medium' detail settings. Conversely, it looks downright crappy at the 'low' setting. I wouldn't want to spend a lot of time playing it on the 'low' setting unless forced. I couldn't honesly say at any time did the whole game feel fluid or completely smooth. There was always an element of jerkiness. That is not to say the game is unplayable; even at around 15fps I would still say the game was 'playable', but only just. When the action picks up and you have a few tanks and some infantry all onscreen at once fighting it out, you really feel that dip down into 8-10 fps territory.
