horrible. Seem to be worse than the previous version with FS9.Anyone agree?

Nope... :-hah

Nope too. But I only got my ATI last week. The 4.5 is definitely better than the 4.4. And this sowith an 'experienced' ATI user statement... Kind regards Jaap

Yes, very bad (stuttering, IQ...)I didn

Thanks for reminding me!I *had* noticed a serious deterioration in FS performance over the past few weeks, but I had been experimenting with various stuff, like the new GA-Traffic generator and new scenery, so I was trying to tweak all that and had forgotten all about the new drivers I installed routinely...now I just went back to 4.3 (Radeon 9700 Pro) and FS is a lot smoother again!Best,Martijn

4.5's are fine on this end. Slightly faster and no stutters at all.Stable too.....Ed GreenKCLThttp://www.panelshop.com/DEV.jpg

I think it may depend on what card you're using. Judging from the few posts here, the 4.5 Cats appear to be fine with 9800's at least.Both the original poster and me have seen improvements by going back to 4.3 on a 9700 pro.Best,Martijn

ONLY UPGRADE IF YOU ARE HAVING PROBLEMS.Chris Low.

Hi, I don

Chris, that's the moral of the story here... :-beerchug

ROTFLMAO.....Guys I have to say that this a weird thread. I usually always use up to date drivers. Having read this though I took the plunge and installed all drivers one after another. The 4.3s, the 4.4s, and finally the 4.5s. I always loaded up the default flight on the runway in Seatlle and flew the same pattern. My card btw is an Radeon 9800XT.There has been no, I mean zero noticable differences between all three driver versions neither in performance nor picture quality. the reason for this is very likely the fact that there is not something real new about these drivers other than specific bugfixes for specific games. So now I really wonder. No offense here, but maybe...I mean just maybe some of you just have a messed up system.Of course your milage can always vary.Alex

Oh , thanks Alex, now I have discovered that all the threads on Rage3d, Driverheaven, Guru3D... are people that could be using Catalyst 2.3 and simply they think that the are using Cat 4.5.Really brilliant.

Well, there is no need at all to get sarcastic here. There is a reason for driver updates and there are differences in certain games. And btw I am not talking about the 2.3 here. I am talking about a series of drivers that all have the same digit in front.I have not answered to this topic shooting out of the hip. I really took the 30 minutes to try all of these 3.And the guys at Guru3d, driver heaven...come on. How serious can I take someone, who is jumping for joy because he has a benchmark increase of 2%. BTW I don't play 3DMark a lot. But I guess to everyone its own. It is just a matter of belief I guess.Alex

Hi Alex, I had my first ATI 9700 Pro in November 2002, the 9800 Pro in summer 2003, and the 9800XT in Winter 2003. I have seen many Catalyst, and if you read carefully my post I say that IN MY SYSTEM, these catalyst 4.5 stutters, and the anisothropic filter doesn

And I said your mileage will vary. So what are we discussing here?BTW why in hell would you want to format your HD when instaling a new driver?Alex
