Comment from: Bradley

i hope not becasue i cant barley run call of duty world at war on my pc i have to turn all the graphics down to low or off and put the game resolution to 640x480 just to play it at full speed and thats not even online it laggs online man to play the newer games you really got to have a top of the line computer now a days and the system requirments show above to play portal 2 are just the minnimum system requirments

10th January 2011 @ 03:50

I have a question, Will portal 2 only be able to be played on the pc with steam? I am a minor and i am not allowed to have steam. so again. I ask, Can I play portal 2 without having a steam account, steam, or steam cloud>

Hey Bradley, get a new computer then. They keep making them for a reason.

Comment from: Sops

Nothing top of the line about it Bradley, you just have an old computer. The consoles have really inhibited progression to system requirements and with 5 years left in this console generation (according to Microsoft) you will get your moneys worth if you get a new PC now.

$500 will buy a computer that can play any of the big title games on maxed settings.

Answer to Matt: Yes is will only be available to play through steam unless you download the game Illegaly...

No. You can buy it the old fashioned way... on a disk, but you'll have to wait a couple of days

Comment from: Plumber

If you buy it on a disc you still have to use steam to play.

Alternatively, you can play it on the Xbox 360 or PlayStation 3. No Steam required.

@Matt, i'm minor too, and i have a steam account and a visa credit card, and i bought some games on my steam account, so, tou can have your own steam acc, but you can get the game on disk form a specialised store :D

I dunno about all the talk about "Just buy a new computer" and "Yours must be old."

I bought mine new last year and I don't have the 3GHz processing power. Every other system requirement in spades. Far better graphics card. Memory is negligible, but that processor... bollocks...

21st April 2011 @ 14:30

Keep in mind 3Ghz is for a Pentium 4, so something like a 2Ghz Athlon would be fine. Else any Core 2 dual core processor is fine.

Runs on my Atom 525 just fine. Of course there's the Ion2 in there as well.

Just for a guideline for other people this works great on my Sempron M100 with an ATI Radeon Mobility HD 4200 and 3 gigs of RAM. Turned down anit-aliasing to 2x and model textures to medium and works at a solid 30 FPS. Sometimes it slows down when GLaDOS is moving a lot of panels around at once.

I have MacOS 10.5.8 but the rest of the requirements I meet. This may sound dumb but could I still run it with 10.5.8 or no?

Hi guys,

I'm just wondering how this would do on an Intel Pentium Dual Core CPU, 2.00Ghz each with 2.00GB of RAM? I'm not much of a PC gamer, but I'd really like to try this one out... Thanks!

Comment from: bolt

why does a mac require a far better gpu than windows? windows requires NVidia 7600 or higher, while mac requires the significantly better 8600.

24th April 2011 @ 12:53

@bolt Macintosh's usually have higher requirements because Mac OS is slower than Windows.

Anandtech had some benchmarks with the source engine on the same hardware and Windows had pretty much double the frame rate across the board.

I have an nVidia GeForce FX 5500 and a onboard grpahics card , so is it possible that it works?

Comment from: AMD PHENOM X6

That graphic card is just to old. I guess the cards they demand on the specs are for minimum. Like someone above mentioned if you want to play games on pc you can build a gamers pc for about 500 if you don't want to spend that kind of money just buy a ps3 or an xbox.

Comment from: Ed

@bolt and @Paul
The reason that Macs need a more powerful GPU is not because the Mac OS itslef is slower, it's because it cannot use the hardware routines of DirectX (DirectX is a Windows-only thing). Any Unix/Linux based OS is stuck with OpenGL, which is slower. (This is also why it is so hard to find a decent FPS under Linux.)

The good news is that the GPU in a Mac still has DirectX embedded on its silicon. Dual-boot your Mac, and you will not need the stronger GPU while running Windows.

@Sean: you didn't read carefully, didn't you, genius? :)
The 3GHz requirement is for Pentium4 only ....
If your pc is 1 year old, you probably have an i3/i5/i7 so it's fine because they are newer than Core2.

Comment from: Sorin

Hello everybody my pc specs are the following :
- intel pentium d325(celeron) : 2.5 ghz (overclocked up to 3 ghz)
- video card : ati radeon hd 3450 (saphire version) 512 MB
- RAM : 768 MB ( i will upgrade this soon :D )
- Total HDD space 500 GB ( so i thing i have that required space available )

Now my question is...the game will run smooth or bad...or between ?

My guess is that il run decent enough so i can enjoy the game itself...em i right guys...or not ?

@Sorin, Your CPU and RAM is low, it probably would not let you run the install.

Can I still play with a 2.8 GHz Processor on low settings or will this just crash it?

29th April 2011 @ 01:17
Comment from: msownzy00

@ Ed OpenGL is better than DirectX. It's slower because the game is optimized to run on DirectX.

Why don't programmers use OpenGL? Because M$ owns the world!

Oh for gods sake. Anyone with a normal computer will be able to play Portal 2. My one year old mid end laptop can run it fine. I'm sure any system bought in the last five years will be able to run Portal 2.

Comment from: Anon

You do NOT need a 3.0 GHz processor, guys. I play this at 1024x768, 90FPS average, using an Intel Pentium 4 2.4GHz.

Also, it doesn't use up much RAM. I actually see firefox using more RAM than this game when I use it. Most of the time Portal 2 has sat around 150 MB of RAM in use.

Comment from: conqerer2

Agree with above. Ive got a Dell Inspiron 1525, runs portal just fine the way I bought it. If ram or memory is a problem, game booster can typically clear that up, but I haven't had a problem with it.

I have an Asus X51RL laptop, with:
- Intel Core 2 Duo T5450 @ 1.66GHz
- 2GB RAM;
- ATI Radeon Xpress X1100 - 256MB onboard.

The game starts fine (main menu), but when I load the first chapter, I can see on the screen only the mouse cursor, and anything is black...what is the problem?

Will Portal 2 run with this Processor?
Pentium(R) Duel-Core CPU T4500 @2.30GHz
Please someone tell me, please. I have been putting off getting it cause I'm not sure if it will run, and I REALLY want to play it. :)

Comment from: simon

you need to be at least 13 years old to have steam, so a minor can also play games on steam.
The reason why they do that is because a huge number of the gamers are minors

Dude my pc is the slowest ever, though I can play portal 1 fine on max setting.
I overclocked my pc, used gamebooster, and tried playing it that way, but it still was laggy, and slow on low settings.
I have a an Intel Express 4 series chipset U2700@1.3ghz
3gig processor.

To run portal 2 in Max setting
You would Need a 2ghz amd athlon 64 with 2 gb ram
or a celron r (d) 3ghz with 2 gb ram
and an nvida 9400 gt card should do just fine

My PC will be able to play Portal 2 soon. I have a Dell Dimension 8300, 2gb ram, 3ghz processor, but my graphics card only has about 64mb of V ram. so yea.
