This option enables you to override the 'memory amount autodetection' of the driver. If autodetection is working incorrect, you can manually set the amount this way. You could also lower the amount of RAM to a lower value than actually there to test with for instance overlay use in applications. So this option is probably mostly of interest to developers. Specify the RAM amount in Mb (use only 'whole' numbers!).<br>

<li>Added capability to driver to run without an INT assigned. Driver will now automatically disable the 'Sync_to_Retrace' function if no INT was assigned instead of not loading/running at all;
<li>Fixed PLL reference recognition (used for refreshrate calculations) and dualhead detection for a number of 'newer' cards: most notably for a lot of GeForce 6200 types! Code is rewritten so it's much less breakable when new cards are added to the supported list in the future;

<li>Added 'force TV output signal type' (called tv_output) to nv.settings: Now you can select Y/C or CVBS output manually in case autodetection fails for your TV set. That might happen in case the TV and/or card manufacturor didn't adhere to the impedance specs that exist for these signals;
<li>Added detection for two new cards: Geforce 7800 GT PCIe (ID 0x0092) and Geforce 7800 GTX Go PCIe (ID 0x0099). While these cards are reported to work, please note that acceleration for these cards is yet disabled;
<li>Added 'force VGA output ON while TVout enabled' (called 'vga_on_tv') to nv.settings: Now the VGA screen is disabled by default for a head outputting to TV. You can turn it on however using this new preset setting. Note though: doing that is considered a tweak which might damage your VGA screen (if it's an old one);
<li>Added custom modeflag for users to be able to select TVout head on a 'per mode' basis. The Dualhead Setup preference panel needs to be updated (to a version newer than 0.03a) to correctly issue this flag.

<li>Added rudimentary NV11 CRTC2 FIFO watermark/burst-size programming to remove/minimize vertical distortion stripes occuring on some cards due to data fetching errors (because of limited bandwidth);
