Why @ 59.78 FPS?

That's right guys...


Computer 1:

MacBook Pro Santa Rosa (2008)

2.4 GHz Intel Core 2 Duo
4 GB RAM
NVidia 8600M GT 256 MB
200 GB HDD @ 5400 RPM

Partitions

Mac OS X 10.6 (140 GB)
Windows XP x64 (55 GB)

Computer 2:

HP dv0000

AMD Athlon 2.2 Ghz
512 MB RAM
Some NVidia Express Chipset, 64 MB
120 GB 7200 RPM HDD

Windows XP Professional 32-Bit

=========================

So here the thing, Computer 2 has a steady 60.00 FPS on Touhou 6 - 10. It can't run the newer games, though. I guess it's because of graphics memory.

(I think the minimum is 128 MB, but isn't that a lot anyway? That's the minimum to run Aero on Vista and Windows 7...) o_0

And on Computer 1, I can run any game, but It's either 59.78 FPS or 59.8 (In TH 11, 12, and 12.5)

I know it's not a lot of difference, but why does it do this? Touhou takes at most 30% of my CPU on computer 1 when it's running. Why isn't it a steady 60.00 FPS despite having better hardware? (Both are NVidia GPU, btw.)

Computer 1 is connected to AC power when I play.

It's probably more likely the graphics chip itself.  The later games need more hardware support for things which your onboard chip lacks.

And on Computer 1, I can run any game, but It's either 59.78 FPS or 59.8 (In TH 11, 12, and 12.5)

I'd say this is more likely timing differences between the computers.  Unless you're actually seeing and noticing slowdown, this basically equals 60FPS.

Also, what kind've monitors are on each machine?

Is your monitor's refresh rate set at 60?

I turned off VSync...

Shit runs at 1132 FPS... (Only EoSD)

Oh my lord....

I changed my Display Refresh Rate to 60.0
It used to be 59.

IN now runs at a steady 60.00 FPS
PCB runs at 60.00 FPS. Just tried the extra stage and the replay is at 0.12 % lag.

I individually changed the setting of EoSD to force VSync. It runs at 60.00 FPS.

TH 10, 11, 12, 12.5 all run at 59.8 for some weird reason with VSync off.

But it's reading faster. It doesn't lag as much when I pause the game, though, so definitely some improvement there.

It's probably fine now.
