CPU+RAM are recommended system or better, GPU is slightly below minimum recommendations. With this setup I am able to run the game at 2560x1600 resolution with the game's default settings which set various options to LOW and some to MEDIUM for 3D features. The game runs between 20-40 FPS with an average of about 30FPS and looks absolutely breathtaking even on LOW/MEDIUM quality. It looks better than many AAA games from the last couple years on ULTRA maxed out. If I were to lower the resolution to 1920x1200 which is what most people are likely using (or 1920x1080 more likely), it would half the number of pixels and probably double my framerate to 40-60FPS which would be even better with minimal difference visually. I have not yet played around with the resolution or graphics options yet but I will be doing so over the next few days and if anything interesting pops up I'll share my results here.

I thought I'd post this here so others who have similar hardware and wonder if the game will work on their system can get an idea of what the experience is like for me at least. In my opinion this game doesn't have low/medium/high/ultra quality - it has high/ultra/super-ultra/holyfuck. :)

I was blown away by how well the game runs on my system. The GPU and CPU is below minimum requirements. I run it on 1680x1050, all post-processing effects on, all settings on high, except water, shadows, and one of the foliage settings (and nVidia Hairworks is turned off). I get 30-40 fps, and it very rarely drops below 30. The PC sounds like a jet engine while running the game, but it's barely audible with the headset on :D

Anybody able to play this with 4GB RAM? :D

(haha, I'm joking, I can barely play TW2 on my laptop...)

Your PC probably would work depending on what resolution you use. The Xbox One version is the absolute worst version though as it runs at only 900p which is garbage.

You got any OC going on anything?
Does a bottleneck appear to be from the CPU or GPU?
Does the game have settings for enabling unlimited VRAM? ;D

I would be very interested to hear from 860m/960m owners about their performance with The Witcher 3 at 1080p, i've just bought a Y50-70 with 960m and 1080p IPS screen.

Nothing is OC'd.
When I alt-tab and look at the task manager, I only see TW3 using 30-40 % of the CPU, so I guess the bottleneck is from the GPU.
I have not seen a setting for enabling unlimited VRAM.

I'm playing it on a GT 730 (slightly overclocked) and 4GB of RAM :)
Everything is at dirt low settings and well it's hard to play, I beat the griffon thats in the first area of the game though.

Thank you! Data is much appreciated! 30-40% CPU usage looks promising for folks with dual core CPUs. Hopefully, it ain't like DA:I and starts on such systems.
Which CPU are you on? Seems CDPR did a (meh)good job on the port !

I have a 4 core AMD(overclocked from 3) running at 3.33ghz each
(I also would not recommend my gpu settings for gameplay, BUT the dialog scenes between characters runs pretty well.)

You know, according to all monitoring software I have, Witcher 3 uses under 3 Gb of RAM, that's less than GTA V. Approximately 2.3 Gb. So if your other specs are borderline, you can actually try it. For the most part, technical side of the game is impressive.

Ok, seems more cores are the way to go. I'm really curious about how this runs since DA:I doesn't even start on systems without 4 or more cores. Thanks for the info!

Game runs very nice on medium at 1080p.

I am and I can, but all my specs are below minimum. I get around 20 fps on all the lowest settings.
