I had read several articles about the FX cards and what I read was disturbing, I wasn't at all comfortable with how Nvidia has lied to the public or cheated on 3dmark 2001 benchmarks (- I got suckered by Nvidias advertising and Hyping for sure)- I'll post a really good post with a few links to online articles about the issues with Nvidia incase your interested in a bit here)
Nope, I didn't have this issue with the 5900 card, I also want to mention here that The Nvidia 5900 card that I had previous, rendered ground textures (When I'm flying chopper) MUCH cleaner & Crisper than the ATI card- with the ati card, I get alot of shimmer in the ground textures in BF42 that makes the textures more "fuzzy, less clear/crisp" looking than the Nvidia card (Let Me stress here though, I DO NOT get the same effects with the ATI card in games like UT/UT 2003/ Trophy Hunter 2003, but I do get the same in Superbike 2001 (another EA title)).
Graphics in BF42 and Superbike 2001 are ,how shall I put this?, Fuzzy, not as sharp, blurry, etc (out about 30-60 or so game feet), in BF42, the textures "Shimmer" or wobble, whereas with the 5900, they were clear as a bell- and the textures out a dfistance that weren't yet rendered fully due to distance, did no such shimmering.
In Ways, I'm Really glad I got the ATI (for instance, I can run games with FAR more eye candy than the 5900, and at higher resolutions), But in other ways, I miss the clarity and sharpness of rendering of the FX 5900.
My hope is that ATI will work on the sharpness of their cards rendering in the future with a bit more potimized cards, but if not, I guess I can live with a bit blurrier graphics
I know this all has no bearing on the grid pattern I'm experiencing, but, I thought I'd just let Ya'll know My experiences with these 2 cards- read this thread at EA to get more insight into these 2 cards if your think9ing about upgrading- Lots of great info in this thread-it's a long thread, but most of the good info is in the second-3'rd pages-
