Hi!
A little over a year ago I bought a new computer, didnt have time to fuss with components so just grabbed a prepackaged Dell (Vostro) with an i7 2.8 Ghz processor and 6 GB ram. Bought Crysis and Modern Warfare 2 mostly just to test out performance and the internal GTS 240 card handled the games fine, got addicted to Crysis and have been playing it regularly ever since.
About a month ago the fan on the GTS 240, apparently of notoriously bad quality, started bonkering out, producing heavy and very random noise regardless of any cleanings I would do so I finally grabbed a new Gigabyte GTX 460 card to replace it. Turned it on and ahh, wonderful silence. However, as soon as I started up Crysis, something was terribly off with the graphics. I had previously played on Low/Medium settings so I cranked everything up to High/Highest instead to see if that would help. All the textures, shadings, water, particle effects etc suddenly turned stunningly beautiful, but something was still horribly off somehow.
Finally I realized it was the edges that seemed to not be antialiasing properly. I played around with the antialias setting a bit, but while it does seem to cause some minor changes between 0x and 16x, not even at the 16x settings do the edges look good. Still very jagged, crisp, sharp pixley edges along pretty much every line, especially where a dark object is rendered against a brighter one. Even the regular white chat text overlayed on the game background is hard to read because of the s***ty antialias. I noticed the nVidia control panels offer some options for manually enforcing antialias and override the settings of individual games, but upping that to the max didn't seem to change anything either.
I reinstalled Modern Warfare 2 just to see if it was specifically a Crysis issue but nope, MW2 looks just as horrible and un-antialiased as Crysis does, jagged crisp lines around everything even on the maximum (here 4x) antialias setting.
Now, I've read online that people have had issues with more recent settings on the GTX 460 card and since the driver that came with the card was (I think) 275.33, I decided to try with what seems to be regarded the "last safe bet" for the 460 cards - the 258.96 version. However, no change, still the horrible edges around everything in both games.
Has anybody else encountered this problem, or have any suggestions of something I could try?
