[Wine] Singularity game has slow video

[doctordruidphd]

I am posting this here because the other posters in AppDB say the game works fine. For me, the video is slow and jerky, not playable at all.

System: Dell XPS630 q9550 dual core-2, 8gm RAM, 2x NVIDIA 9800GT, lots of disk space (meets all system requirements)
kUbuntu-10.04, all current updates, nvidia 195.36.24 driver. Have tried kde, gnome, and lxde desktops (compositing disabled), same problem in all cases.

I tried installing in a clean .wine directory. Without installing directX from the DVD, I get the following error messages:

[code]fixme:ntoskrnl:KeInitializeTimerEx stub: 0x110ff8 0
fixme:actctx:parse_depend_manifests Could not find dependent assembly L"Microsoft.VC90.CRT" (9.0.21022.8)

[/code]

The missing dll's do not seem to be available in winetricks. So I installed DirectX from the DVD, and the game runs, but video is too slow to be useable. 

This system does run other games (Witcher, Oblivion, Wolfenstein) in their own .wine directories just fine, so it should be working. I notice the video tweaks that used to be in the registry under HKCU/Software/Wine/ are no longer there.

Seems I missed something. Any ideas?
