Hi,

So it works for you in s3d, right? It's just that bad ghosting you're talking about. I don't know how to fix that but here's my notes on The Sands of Time:

-------

Prince of Persia, The Sands of Time: old-school nvidia


Conclusion/recommendations:

s3d works but software ghosting can be very bad and HUD can also be a problem.
Use drivers 78.01 or single core mode with 91.31 or greater.
Usable bad HUD, Help-text too close/offscreen, Health-bar too close but usable.
Use smaller 3d settings with large-screen projector to help solve HUD-too-close problem.
Game needs autoconvergence in order to look/work better in s3d.


Game notes:

Camera - a 3rd person game but has temporary 1st person and far-away area views. Mouse controls camera angle and zoom but not character movement.
This is the one where he starts in a battle in a castle wearing baggy white pants. ;)


nvidia issues: tested with 7800GTX

1) freezes on 3d toggle - fix: use single core mode
(drivers 91.31 and 162.50.)

2) HUD - bad depth - no fix but usable if you don't need on-screen help-text.
Details: Help-text offscreen, Health-bar too close but visible.
No plane control and setting HW-TnL off causes crash on start.
Workaround: Use smaller 3d settings with big-screen projector to help solve HUD problem.

3) Software ghosting - no known fix yet.
Explanation: You can see ghosting in a 3d screenshot even when veiwed in 2d.
Workaround: Converge on character.


3d settings notes:

3d settings are in Registry under _NewFakeLink until next "_NewFakeLink" game is run and Convergence is changed and saved.

HKEY_LOCAL_MACHINE\SOFTWARE\Nvidia Corporation\Global\Stereo3d\Gameconfigs\_NewFakeLink

StereoConvergence = 40930822 hex
StereoTextureEnable = 1 does not seem to help any.
Separation = 18% on a 17 inch CRT (set this in the nvidia "desktop right-click" control panel)


miscellaneous notes:

I haven't played this game much so it's possible that more s3d issues show up in later levels. Nvidia's game-notes say that explosions, fire, and lighted objects are 2D.
Can play with various effects enabled.
PoP, The Two Thrones, Special Edition includes 2 more games (Sands of Time and Warrior Within)
DX9, 1.25GB hard drive space, from 2003
