TI4200 64mb vid mem usage

I have a ti4200 64mb 250/500 o/c to 280/560 on a Athlonxp2000 o/c to 2200,
512mb ram, WinXP pro.

What i would like to know and it will most likely apply to most 64mb cards
is the what amount of video memory is used by recent to current games. Some
games i have like Call of Duty will run fine with texture resolution set to
normal, fairly good at high and studdery at extra high settings. At the
highest settings just how much video memory is it trying to use? I know game
engines use up so much video memory for different things like pixel shaders,
buffering etc but from what i gather high res textures use up video memory
the most. My main question is on a 64mb card is there any tweaks or options
in game or with the drivers that i can change to free up more video memory
to allow games like COD to run higher resolution textures more smoothly?

Video memory usage is a complex and interesting subject. As you are
learning, it's a unified 64M that accomodates the frame buffer and the
texture data, among other data.

This link is a cool tool that helps you quantify the amount of memory
required for running an application at a certain resolution, buffer amounts,
texture requirements...while it isn't perfect, it's intersting and
informative and helpful to your question:

To directly answer you: Yes, there are IQ (image Quality) settings that can
prioritize texture quality over other IQ elements (such as resolution) to
achieve higher FPS. However, each game/application has their own specific
tweaks, and only you can decide if the tradeoffs are worth it...based on
your monitor/other hardware, perceptions, desires, etc.
