Graphics Vendor ID 0x10de Device ID 0x 863 WebGL Renderer NVIDIA Corporation -- NVIDIA GeForce 9400M OpenGL Engine -- 2.1 NVIDIA-7.12.9 GPU Accelerated Windows 1/1 OpenGL AzureBackend quartz Actual results: Safari's score is considerately higher: Benchmark Score: 2215 Average FPS: 47 vs. Nightly: Benchmark Score: 899 Average FPS: 19 Expected results: I'd expected them to be about equally fast.
I would be curious to see this comparison again on 10.6 where safari doesn't use the lion undocumented API.
Sadly I don't have 10.6 installed for a comparison. I just tried the same benchmark using Google Chrome 16.0.912.77: Benchmark Score: 991 Average FPS: 21 From that perspective Nightly's performance isn't even so bad. Though I don't know what graphics backend Chrome uses on the mac.
Thanks, we're already working on some patches to close that gap. We're hoping to land them in Firefox 13 if all goes well.
I have 10.6 on my laptop still here is what I got with Safari 5.1.4: Benchmark Score: 1088 Average FPS: 23 FF Aurora (12): Benchmark Score: 1337 Average FPS: 28 Benchmark #5 (spinning ship with green lasers) was very slow ~11fps pushing the average down I think for FF. The other tests were all noticeably faster in FF then Safari.
