Installation and Drivers Of The Siluro GF256 GTS 64
Cool breeze but nothing too exciting

The Siluro GF256 is a little too generic for our liking, as far as software goes.  You do get the added bonus of the bundled in games, something that is falling by the wayside with most manufacturers.  This is a nice touch but the games, Test Drive 5 and Shogo are a little out dated.  Furthermore, the driver suite that Abit has on their install CD ROM was based on a very old version of the nVidia reference drivers (3.93 I think) and not of much use these days, especially if you want FSAA. 

This is a shot of one of the Abit control panels.

Yes indeed, those are version 3.93 Detonator drivers there.  There isn't much else to comment on here except to say that we hope Abit revises them to at least the currently released 5.22 version.  The Abit Siluro web site has no updates listed for the card either.

However, also on the driver CD is a full version of WinDVD which is an excellent DVD Movie Player.  This augments the great DVD playback capabilities of the card.

So we moved on to the nVidia 5.32 version Detonator drivers, in an effort to be able to over-clock the Siluro GF256 GTS and tweak it for FSAA etc.

Full Scene Anti-Aliasing (FSAA):
First let's look at how nVidia has been doing with respect to FSAA since the GeForce2 launch.  Things certainly have improved somewhat, from a driver support perspective.  Here are a couple of FSAA shots first in OpenGL driven Quake3 and then in Direct 3D Driven USAF from Electronic Arts.

Smooth Sailing

Original TGA Images can be found here for the Q3 shot and here for the USAF shot.  In our eyes, the Quake3 shot still is not up to par with 3dfx style FSAA.  This shot was taken with the "enable full scene anti-aliasing" button checked off, under the OpenGL control panel.  There is only one setting accessible to the user, on or off.  We have heard of ways to tweak the level of FSAA in OpenGL games but are unaware of how to go about adjusting it.  It is also not obvious to the average end user ( it is some sort of registry hack ) so we felt it was only fair to judge based on what is available out of the box.

Direct 3D FSAA is another story however.  Things are looking up in this area for sure.  Here is the setting we used for the USAF shot.

This is nVidia's setting for 4X FSAA.  As you can see in the above shot with Janes EA's USAF, things are pretty sharp indeed.  As a side note, FSAA is definitely less useful in games like Quake3, where you are less likely to notice its advantages with the fast pace action going on.  On the other hand, good FSAA in a Flight Sim like USAF, is a god-send.  At 1024X768 with 32 bit color, you will be happy to know that frame rate was excellent and the game was totally playable.

And on the eight day God said "let them over-clock"...
