The specs doesn't matter much. Trident is known for making standard graphics cards and that one shouldn't be the exception. Besides, the plugin work with Direct3D.
Now i remember that GTA 3 have a particular problem that can be relationated with this one.
"Windows XP + nVIDIA based cards (*possibly* other brands):
We have found a possible problem with Windows XP that manifests itself
as graphical problems both in the game menu and also during game play.
We have traced this problem to be a Windows XP problem.
Technically this problem is solved by the use of a newer version of
d3d8.dll than is shipped on CD with Windows XP. (The version on the
Windows XP CD that has problems is 5.1.26000.0 – versions tested
without error include 5.1.2600.15 and 5.1.2600.29)
Currently the only way we know to update this dll file is to install
the Windows XP Patch: “The Computer Cannot Enter Standby or Hibernate
If a Direct3D-Based Screen Saver Is Running (Q306676)” downloadable
from the following Web Site:
http://download.microsoft.com/downl...Q306676/WXP/EN-US/Q306676_WXP_SP1_x86_ENU.exe.
This update may in the future be available as part of an official
Windows XP Service Pack, a Windows XP Compatibility Update, or possibly
a DirectX 8.1 update.
Power VR *Kyro 2* video cards
We have been unable to fully support this card due to the nature of
rendering on this card, and as a consequence some texture effects do
not display correctly, though these are minor. We recommend this video
card is used with a 32 bit screen mode, as in 16 bit we discovered a
rare depth buffer issue, which is solved in 32 bit. We would also
recommend making the following settings changes:
=> Go to the advanced display properties dialogue
Select the Direct 3D page, and create a new profile for gta3.exe (pj64.exe),
Then inside this profile:-
DISABLE W buffer
ENABLE external depth / stencil buffer format
ENABLE Direct 3d / stencil buffer format
ENABLE depth / stencil buffer format
ENABLE depth / stencil buffer loading
