<ul>
<li>Fixed GeForceFX 5600 and FX 5700 monitor 'refresh out of range' / shutoff fault. nVidia changed the pixelPLL for the NV31 and NV36;
<li>Fixed acceleration engine restrictions code to adhere to GeForceFX 5600 restrictions: those are still NV20 style for this card;
@ -18,7 +18,8 @@
<li>Improved startup code: this should (could) fix random trouble on some cards like for instance hardcursor trouble on especially laptops;
<li>Added dualhead support (use Mark Watson's 'G400 Dualhead Setup' from BeBits for now): Note that dualhead switch mode still has to be setup, and overlay is fixed to the primary head for now;
<li>Updated mode granularity and max virtual size checking/limiting to adhere to new CRTC setup for dualhead cards;
<li>Added dualhead support for 8- and 16bit colordepths.
<li>Added dualhead support for 8- and 16bit colordepths;
<li>Fixed move_display distortions in virtualscreens especially visible in 8-bit colordepth (for both heads).
