Moving from Nvidia to ATI - any troubles?

[Helmut_AUT 0]

Hi all

Upgrading my whole system, the 9600GT gives way to a 4890 (unable to find a 5870 anywhere).

I plan on running CCC with default 4xFSAA, 4xAniso set since many of my older games do not support FSAA selection within the game menu.

With Nvidia, forcing FSAA trough driver caused Artifacts in Arma2. Same for ATI?

Any other problems I should be aware off with the combination of Win7 64bit, latest catalyst and 4890?

something aboutArma's texture sizes doesn't like ATI or so I've read somewhere.

Search the forums! :)

as long as you uninstall your drivers before installing ATI ones you'll be good.

And no ATI don't have texture issues, ive got ATI and have no issues with A1 or A2, my mate has Nvidia and A1 wont run and A2 is laggy altho thatd be due to his slow duelcore.

The few times i've tried going from Nvidia to ATI(mainly because of the price difference) i've experienced problems, if it wasn't one thing then the other!

Now i stick to Nvidia no matter what on the paper awesome gfx cards ATI comes up with :)

I think the texture thing Master means is related to the 8GB RAM which leads to wrong detection of GFX Memory.

JW, I'd have stayed with Nvidia, but if I can't get a GTX285 for over six weeks anymore it's really their problem to lose a customer.

use both company's cards. Both run fine, both have quirks, both have something better than the other. Prefer IQ from Ati right now.

I prefer nvidia for their more stable cards, longer life cycles and better drivers. That said to be on topic I think there is only one texture related hitch for ATi cards when it comes to Arma2 and its only minor.

Now that is a complete fallacy and typical fanboy opinion. ATI do have driver issues sometimes, but so do nvidia.

The "longer life cycles" and "more stable cards" is completely baseless.

I may sound like some ATI-fanboy-rager, but in reality I just hate it when people who are misinformed, misinform others..

Okay, I loaded everything up on the new computer - and I DO have troubles.

Even in the option screen (the camera panning over the Aircraft Carrier) I get jerky movement. My framerate jumps from 60 to 45 and right back up every second or two.

It's insane - obviously the HD4890 should run this perfectly fast, but something causes performance to break down at regular intervals, leading to a jerky game. I'm at a loss - spent 1400EUR on this new box, all drivers up to date, Win7 64bit, an i7-860 and 4GB RAM - plenty of power.

But A2 jerks.

have you installed latest beta patches?

leave your CCC on default settings except;

enable advance AI, and the rest on application settings.

If all that didn't help, download and try Ati tray tools. I no longer use CCC but ati tray tools, make sure you download the beta version of ati tray tools. I also end task CCC just to make sure no conflict arises.

Okay, I reset the GFX options down, then up again, and it seems to improve.

What it feels like is actually as if loading terrain causes this at irregular intervals. But I'm playing from an SSD with 200MB/s read speed?

It's not painful now anymore. But there's definitly a jerk that wasn't there before, a sharp drop in framerate.

No beta patches yet, I loaded the same 1.02 as I had on my old system (never got around to updating for 1.04).

CCC is at default.
