Usually spec requirements are more guidelines than actual benchmarks, so taking in consideration your system I say there is a 99% chance that you will be able to play at maximum quality with a decent framerate.

If not you can always tweak it, there is rarely a significant visual difference between AAx4 and AAx8, meaning you might not even notice what type of AA you have until you look at your settings. :)

Dear Friends

It's working only on High Details not Ultra Details on my system and between 24-32 FPS on 1920x1080.

I have clicked Auto-Settings options.

Sincerely

E8400@3.6GHz + 6GB RAM + 5870 1GB + Win7 HP 64bit

high spec: high 30s at 1080p with vsync enabled
ultra spec: 7-8 FPS (didn't test for long as it was obviously totally unplayable)

edit:
moving to ultra spec with disabled ubersampling and SSAO, i get high 20s @ 1080p

I'm using vsync on. Will that affect gameplay? Card runs cooler (GTX 570 ASUS DirectCU II)

yeh it's the ubersampling that does it. I have a 5970 and an i7 920 at 3.8 ghz and I get 10-15 fps on ultra with ubersampling settings. If I choose ultra settings with the ubersampling off I get 25-35 fps. High I get 30-35 fps, med 35-40fps and low 40-45. The ATI scaling is total F'ed up it seems and as usual I'm guessing the devs basically only worked on the Nividia version to ensure stability and performance. It seems I won't be playing The Witcher 2 till next month then -_-. The same thing happened with brink actually, getting constant 30 fps rather than the 60-100 I should be.
I really can't be bothered paying for broken games at release, I should really just learn my lesson and wait a good 6 months when they're cheaper and the bugs are fixed, as I seem to be getting zero benefits from being an early adopter. I'd prefer if they just had a bit more dev time.

Edit: Also yeh Gidzin it will, if you have under 60 FPS during gameplay then you're adding an additional load to the system that will give you no benefit. Vsync is just used to ensure you doing get screen tears (the tearing lines when you move your camera too fast when you have 60+ fps) if you have 60+ fps if caps it at 60 so you don't get any screen tears on your screen. However if you're not getting more than 60 fps then you're just wasting resources with that setting as it provides no benefit.

Ok, so I'm running the game at max setting, except for ubersampling and SSAO is dissabled too. Running at 1600x900 on the following system

Windows 7 x64
AMD Phenom II X4 965 BE
AMD Radeon 6850 1GB slight OC
8GB RAM G.Skill Ripjaw

The game is running very smooth. The odd scene I will notice a different feel in the mouse movement meaning an FPS drop but I imagine no lower than 25 FPS or so as I can't see it chugging. I'm extremely impressed with how well the game runs, and not to mention how damn beautiful it is!

Can't say you're being fair. Just because it won't run with everything set to max on your comp it doesn't mean you got screwed. I've seen much worse releases, but this one already got me drooling. It's going to be even better playing through this one than it was for the first one. Provided they didn't mess up the storyline of course.

Thanks for the tip about übersampling though :)

I love how people are completely ubering it up whilst I'm stuck running complete minimum settings (which are beautiful regardless!) and getting 15 fps. Can't say I'm not a bit at fault, but I thought minimum meant "minimum at 30 fps" at least.

I spend a very significant amount of money on my rig, and I do expect it to play everything on max settings for the amount of money i've put into it. It has a wide variety of super high end components and I use a 120 hz 3D monitor to utilise the additional FPS (feels significantly smoother). It won't ruin the game for me, but I will wait till I can utilise my gaming investments.

I have no qualms with CD projekt they've done a great release, it was more directed at the graphic card companies and their relationship with the developers. Though I still think they should spend more time stabilising the product so that it works equally well for both graphic card manufactures. I may just give up though and get two GTX 690s next year and be done with the ATI brand, as i've found I regularly get the shaft driver wise from them.

Dear Friends

What is SSAO?

How to completely disable AA, AF in Catalyst Control Settings?
Here is an information to do that on ATI cards: THREAD

Best regards.

Wikipedia is your friend :).

"Screen Space Ambient Occlusion (SSAO) is a rendering technique for efficiently approximating the well-known computer graphics ambient occlusion effect in real time. It was used for the first time in a video game in the 2007 PC game Crysis made by Crytek.""

"Ambient occlusion is a shading method used in 3D computer graphics which helps add realism to local reflection models by taking into account attenuation of light due to occlusion. Ambient occlusion attempts to approximate the way light radiates in real life, especially off what are normally considered non-reflective surfaces.
Unlike local methods like Phong shading, ambient occlusion is a global method, meaning the illumination at each point is a function of other geometry in the scene. However, it is a very crude approximation to full global illumination. The soft appearance achieved by ambient occlusion alone is similar to the way an object appears on an overcast day."

Do NOT guess... use fraps or something similar to document what fps you're getting.

I'm on the lowest settings possible and i'm having horrendous performance.

Dear Synboi

Yep, I know, here is such great people support that I thought that anybody will answer more quickly then I even check Google My Friend :)

Thank you very much.

I have disabled SSOA, Ubersampling and I have got 32 FPS 1920x1080 fullscreen, windowed mode 35 FPS. Of course everything is from Ultra High Profile.

OS: Windows 7 x64
CPU: Intel i5-750 2.66 GHz Quad Core
RAM: 4 GB RAM DDR3 1333 MHz
GPU: ATI HD5850 1GB
HDD: 1.5 TB

Best regards.

PS. I am waiting for Polish language pack... It would be great if it be available today.

Why is it so important that he doesn't guess? I mean, as long as he considers it smooth, why bother? It would matter if he were benchmarking, but that doesn't seem to be his intention.
