onboard intel graphics cards would be very underpowered to run that game , even with 3d analyzer

Hm, far shot, but you could try enabling/disabling Vertical Sync.

I've seen a very few games that exhibited sluggish behaviour (Controls) when it was set wrong for the Game's Engine.

Also make sure your Video, Chipset and especially Audio Drivers are 100% up-to-date.
I've seen (extremely rare) Audio Drivers drag down System performance when running on old Drivers on more modern games.
A good Idea would also be to test different Sound Options, if available in the Game's Sound preferences (e.g. turn off Special Effects like EAX, or reduce number of simultaneous Sound effects if possible)

As a last ditch Trial&Error attempt, you could try playing with the Hardware acceleration levels for Sound and Video. It sometimes helped in such situations.

Other than that, see if there's too much Resource Sharing going on in the Device Manager. Many Audio/Video Drivers did not like sharing IRQ, so Disabling all unused Devices in the BIOS is a good start the help that. Enable ACPI if currently disabled to assist IRQ sharing (if Win98 or later is installed).
