Yeah. NVIDIA dropped support for that one a long time ago. I think
Isaac and Jarod were suggesting a new video card, not a new driver. You
should be able to get a GF4MX440 or (even better in case you ever do
HDTV) a GF5200 for $40 or less.

I'm guessing that "no way out" means it's not a usable solution. If so,
I'd agree (and say that a new graphics card is the solution).

You can change:
Guide Shading Method
* Alpha - Transparent (CPU Usage - High)
* Blender - Transparent (CPU Usage - Middle)
* Eco - Transparent (CPU Usage - Low)
* Solid (CPU Usage - Middle
and
CPU friendly preview of recordings
When enabled, recording previews will play with reduced FPS to save CPU.
and
Use Transparent Boxes
If enabled, the Watch Recording and Delete Recording screens will use
transparency. Disable if selecting the recordings is slow due to high
CPU usage.
But it probably still won't help enough for that card/driver combo. I
would say spending $40 ($20 with a good sale) for a better graphics card
is a better idea. (And, if you're not in the US and can't get the card
for a reasonable price, I can't suggest any cheap alternatives.)
