<p><h2>Changes done for each driverversion:</h2></p>
<p><h1>head (0.16), (Rudolf)</h1></p>
<p><h1>head (0.17), (Rudolf)</h1></p>
<ul>
<li>Added AGP mode capability on AGP cards along with the option to block it in nv.settings. No GART and AGP aperture support; but if your card and system AGP host bridge support the 'fastwrite' (FW) feature, you'll notice a nice speedup of mostly unaccelerated graphics. Tested Quake 2 in software rendering mode over here using timedemo1 with demo1.dm2: framerates jumped up to 140% of the 'original' in 'just' AGP2.0 4X mode!<br>
<strong>Note please :</strong> You need the new AGP kernel driver I setup for this feature, without it you will remain using PCI mode as usual. This AGP driver will be released seperately asap: it's almost ready.
<li>Updated CRTC memory granularity settings on TNT2 and later cards to reduce use of card internal bandwidth: this should minimize or prevent distortions on cards that have limited bandwidth available (especially on older cards). Note: doesn't actually fix the problem! (to be continued...)
<li>Updated CRTC modeline tuning for panels: this should fix the 'right-shifted' picture on some panels in their native modes;
<li>Fixed BIOS ROM dump (to file) option.
<li>Fixed BIOS ROM dump (to file) option;
<li>Fixed GET_TIMING_CONSTRAINTS and GET_ACCELERANT_DEVICE_INFO accelerant hooks to return valid data; updated modeline checking and modification code (used by ProposeDisplayMode) to adhere to one more timing constraint.
</ul>
