There is a RC of the 11.5a hotfix drivers (well it is the third RC to be precise) You can find it here: http://www.ati-forum.de/files/Downloads/Driver/Catalyst_11-5a/amd_catalyst_11.5a_hotfix_8.85.6rc3_win7_may16.exe (I haven't tested it as my HD 6850 runs the game smoothly but maybe it helps you folks)

Dear Friends

I have got ATI 5850 and those steps I have completed and my FPS goes up:
1. Open in Launcher Video and Language.
2. Click Advanced Options.
3. Click Ultra Details.
4. Click 1920x1080 and fullscreen enabled.
5. Disable: Ubersampling and SSAO.
6. Everything leave as it is.
7. Open Catalyst Control Center there:
- AA: application controled
- AF: application controled
- A.I.: middle value (not the highest)
- MipMapping: middle value (not the highest)

ATI Drivers: 11.15a

Launch the game and you will have 24-35 FPS with Ultra High Details and 1920x1080 fullscreen.

To have more FPS, change fullscreen to disabled.
Best regards.

Sincerely

Am i the only ATI user that doen't have any issues?
My specs:
AMD Phenom II X4 940 Black Edition
4 GB RAM
Radeon 5870
Win 7
Everything is as smooth as silk on high settings without ubersampling of course.

My wife runs it on low settings on dual core, 2 gb RAM, Radeon 4870 and everything is fine.

The AMD hotfix was updated before this was posted on their site: So I doubt it's addressed in that update yet. Personally I've installed that hotfix before the latest update to it (RC3) and saw no change in the game's performance.

why is everyone disabling SSAO? in the readme:

- SSAO (Screen Space Ambient Occlusion): lighting effect that is important to the game but unfortunately places significant demands on the GPU.

sure it can give some fps boost but at what cost? LOL
the game/drivers needs updates, no matter what card you have. I have a 560ti and there is no frame difference at all even in LOW or HIGH settings... I am stuck like many in the 27-34fps area... SSAO makes no difference at all , on or off.

@Summit:

define "fine" , how many fps are you getting?

Not the only one. I posted in another thread. I have a 5770 w/ 1 gig VRAM, with a Phenom 2 965, 4 gig ram. Everything is maxed out at 1600 x 1220except uber sampling and it is smooth as butter for me.

i5 2500k, HD 6970, Win 7 64, 4GB, 1680 X 1050

Smooth as butter on high (minus the shiny stuff like bloom)

I'm with Summit, I am using an HD4850 with whatever driver were stamped 5/9/2011, and a 2core 3Ghz CPU on XP, and I got everything at ultra but for uber, blur (hate blur), dangling (whatever that is), and AA (don't need it on a native 1920x180p display) and everything is running fine.

As for FPS, I have no idea; I never cared about that. To me, it's either a ) the game is smooth, or b ) it isn't., and my game plays smoothly, no lag during fights or when a lot of NPCS are on the screen, or when turning, etc. Just smooth video.

The 2 things I am wondering about all the issues is, if people are running the game other than 1920x1080, and if the have a progressive display or not. Maybe 60 fps are needed on interlaced displays, but shouldn't be the case with progressive displays (at least I don't think so).



The one thing

Some ppl consider and see 20fps as smooth, others 30 and other need 60. It varies from person to person and there is nothing wrong whatever value someone thinks as smooth :)

download fraps it's a 2MB program that displays fps and see what you get out of curiosity :)
I am not trying to discredit you, it is all a matter of someone's perception... I get 27-34fps and although the game is certainly playable it is not enjoyable for me.
I have seen it running in the 40-60 range, way better experience

Same system specs. Was just running it with fraps (Flotsam and the forest area) not dipping below 50 max 80 fps.

Phenom II X3 720
Hd 4770 (Overclocked to max in Overdrive)
8 GB Ram
Win 7 64bit

Game runs satisfactory at 1920x1080 with most things set to low. Most texture related stuff has been set to medium because that impacts visuals the most in my experience. Shadows are on medium as well, iirc.

However, I have only played the prologue this morning, so things might be different in Flotsam.

No "hard" fps data to offer, cause I do not care that much. Would estimate roughly 20-30 average. Probably not much lower, as that usually impacts gameplay for me.

[edit] Might try to up the details somewhat this evening, but actually I would rather play the game than try to capture reliable fps data ;-)

Hmmm... I've got a notebook w/P8600/4GB Vista 32b and an ATI Mobility Radeon HD 4850 512MB GDDR3 and see some stuttering. TW2 defaulted me to medium settings and I just ran it at that with no tweaking yet just to play a few minutes of the game. (I still need to finish my current TW1 game first as I'd like to use the finished save from that for TW2.)

(Remember this series of mobilities (48XX) were IDENTICAL to the desktops just with slightly lower core/RAM clocks... after that AMD went back to castrating the mobile GPUs again...)

I'm running a bit older driver though as I don't use windows for much other than games.

I'm playing on a 5870 1gb in Windows 7 64bit no issues, great framerate at high setting.

I have the same card, it runs fine on medium but doesnt like high, I think thats due to having a dual core though.

No your not the only one,my spec i5 3ghz 8g ram ATI 5870 x2,55inch samsung amoled 3DTV @1080p ultra setting with UBER OFF 40FPS+ runs great looks great.
