View Full Version : 66.31 WHQL borked, bilinear only in OGL?

I recently started using the 66.31 WHQL drivers and just noticed a major problem. I just started a new game of NWN HOtU and it looks like it is running in only bilinear filtering. I am playing at 1600X1200 with 4XAA/8XAF in high quality mode. The mip-lines are extremely distubing and don't appear filtered properly. It makes me feel like I am gaming on my old V-2. The mip-map line moves closer and farther as you zoom in and out. It is very annoying just moving around. Changing the all settings does not help a bit. It's like one of the filtering optimizations is stuck on. Some pics below showing the mip-map line cutting across the corner of the carpet/floor and a link for the full pic it came from. Note the link for the full pic is 365k because of the resolution I was gaming at and with any more then 30% compression it washed out the mip-map line. It is actually much worse then the pic shows when you are moving. The problem went away completely when I went back to the 61.77 drivers.

66.00 Forceware has some optimization that can't be turned of making mipmap transitions look like ****. However according to my eyes and testing, 66.31 does not have this problem, at least on my system high quality disables all the "optimizations".

[edit: removed pictures]

As you can see, colored mipmap transitions look smooth, unlike they did with 66.00. Could be game based though, but I haven't seen the bug in any game I've played with these drivers. Bad quality of pictures can be explained by JPEG compression, I decided not to waste my server's bandwith too much.

It could just be game specific. Changing to High Quality etc. does not change any of it though, it stays bilinear. Funny thing is I just noticed one other thing that was bothering me with the 66.31 drivers. There is a awful lot of moire even in high quality which I can see in your first pic on the floor. It is even worse in NWN. The moire problem disappears with the 61.77 drivers in NWN for me.
