Following Earth from startup location, watching M 74 at 16' FOV, today (the Moon is near)
Smallish default window: 48fps
Maximized window (1680x1050): 16fps
Fullscreen (1680x1050x32): 20fps
Default optimizations in the sln, release, VC++2008 SP1, XP SP3
Core 2 Duo E6550 @ 2.333 GHz on a DG33BU board. Nvidia 7300LE, PCIE, 512MB.
sorry, I now discovered that compared to my earllier standard benchmarks there was a leftover 2x AA
still active. This costs speed, of course...
Now the rate is higher, but still significantly lower than without Eigen. Sse2 optimization
in addition gives these rates (Core2Duo 2.0GHz):
1.6.0final: 72 fps (fullscreen) No SSE2!
Eigen 4767: 53 fps (fullscreen) with SSE2
all with M 74, 16' fov
My rates for Eigen, rev 4767 are quite comparable to yours, but with 1.6.0final, they were significantly higher! You did not show your corresponding rates for comparison.
. With 2xAA switched off and NO SSE2
, now the rates of Eigen 4767 and 1.6.0final are about comparable: ~70 fps in fullscreen for M 74 16' on my Core2Duo 2.0 GHz.
