HiI use to play FS2004(FS9) not FSX and I am planning on upgrading my graphic card from ATI Radeon x1950pro 256mb to MSI Radeon HD4850 512mb so I wanted to know if anybody of you guys have this card and which Catalyst software you are currently using for the FS2004(FS9) to work well because I read in some posts that there are people who had problems with this card especially with the antialiasing,So I hope you can help me,Regards,Victor

Hi there,Not quite but similar... I have a HD3850 512Mb. On my system, using FS9 and XP (32bit), I have found that newer catalyst drivers newer (8.5-8.10) do not allow switching between fullscreen and windowed mode while some older ones (8.0-8.2) have problems with the anti-aliasing. I am using 8.4 drivers with no problems at all... Of course I don't know if your (newer) card has the same issues...Geoff

I had a 4850. It seemed to worked just fine in fs9 and I didn't notice any AA problems, but I was in full-screen mode too. But I use fsx instead of 9 so I didn't fly around in 9 much. In fsx it had more scenery shimmering than the nVidia cards and performance (fps) was on-par with the nvidia ones in clouds.3D slider was on quality, fs settings AA and tri. These was with Catalyst 8.10-Kevin

Hi Victor,I just made the jump from an ATI X1950pro to a Visiontek HD4850. I am using the current driver from the ATI website (8.11) with no problems so far. I am using it for both FS9 and FSX with a noticable increase in performance in both sims. I am not overclocking though. That might be the source of some of the problems that have been reported.Hope that helps.
