If you can't run GL3 then it's time for an upgrade.

Most of my friends that I got to try unvanquished are able to run games like L4D2 fine, and half of them had computers under 2 years hold.

That can't be true, any mid-range computer should be able to run unv in GL3 renderer.

That's what I would have though.. o.o

My sisters laptop can run GL3 but I doubt it could run l4d2

It is true.
One of them bought a computer just last year and it couldn't even run GL3 and he was like "gay game" etc. He can't reach the main menu with GL3.
My current computer is 3 years old, although I don't know when exactly it was bought. It can't reach the main menu with GL3.
My previous computer (the one that takes over 3 minutes to load simple atcs on trem) doesn't support GL3 either.
Another friend's computer is about 5 years old, it CAN reach the main menu with GL3, however can't get past the map loading screen.

I don't know the other's computers so I don't know what actually happened with theirs, although some of them can run trem fine at 125+fps.

It doesn't matter how old it is. I might have a shit laptop that I bought this year, but that doesn't make it mid-range. What are his specs?

The requirements for running GL3 are extremely low.

The bare minimum for getting it to run is support for OpenGL 2.1 that isn't buggy.
OpenGL 2.1 is 7 years old now, and is about the feature equivalent of Direct3D9.

The GL3 renderer itself is pretty fast. It will easily hit the capped 125fps on even integrated graphics cards from AMD or Nvidia.
I have personally run it on a 6370M with no issues.
The APUs from AMD also run it very well. ( These are aimed at the low-mid range PC market )

The biggest issue is drivers.

On Linux, I would avoid the open source drivers at all costs. Their performance with any code that uses GLSL is absolutely abysmal.

I would recommend using an Nvidia card with the proprietary Nvidia driver.
The second best option would be an AMD card with fglrx. This is a second best option because fglrx doesn't currently give quite as much performance as it should.

On any OS, I would stay away from Intel graphics cards. Their OpenGL performance is equally bad no matter what OS you use.

On Windows, practically any Nvida or AMD graphics card made in the last 4 years should run GL3 reasonably.

On Mac, the situation is less clear to me. There have been issues with their glsl compiler, but those have been resolved.

I'd say the biggest worry is Mac doesn't have an OpenGL context better than 2.1 unless you are running Mac OSX 10.7 or later.
Mac OSX 10.7 or later adds an OpenGL 3.3 core profile context, but we can't currently use that due to a number of reasons.

Another pressing issue is once more graphics driver bugs.
We seem to be getting a lot of reports from Mac users of rendering problems with otherwise perfectly capable graphics cards.

TLDR:
System requirements for running GL3 renderer:

Minimum System requirements:
CPU: 2.0 Ghz
GPU: OpenGL 2.1 capable
RAM: 2GB

Recommended System requirements:
CPU: 2.0 Ghz
GPU: OpenGL 2.1 capable Nvidia or AMD gpu with the vender provided graphics driver
RAM: 4GB

Disclaimer:
I have not tested every Nvida and AMD gpu in existence. I am merely extrapolating based on low to mid range cards I have tested and the reported experiences from other developers with other graphics cards.

These requirements are based on the current state of the GL3 renderer. They may or may not change in the future.

I have no idea what my friend's GPUs are but my two computers that i tried unv on:
CPU:1) t2400 1.83Ghz (x2)
2) t660 2.20GHz (x2)
Graphics:
1) GM9somethingerather
2) Intel series 4 mobile chipset family
RAM:
1) 504MB (It still ran unvanquished on GL though, even though its memory took up about 800 MB, probs went to virtual memory bank of some kind and ran faster than my current computer once loaded specifically on unv)
2) 2.96GB (opposite of my other computer: runs low fps on unv, loads hell fast)

[Amazonian1515]

My 2009 iMac can handle L4D2, but not Unva on GL3. Awkward.

[seana11]

I can also handle much better looking games than Unv, but GL3 still refuses to run.

:D

That was helpful, guys.

My computer has a 2.7Ghz processor with integrated intel graphics, and 512MB of RAM. I do not intend to upgrade any time soon other than maybe another 1GB of RAM and a ($5) 128MB video card. There are good games out there that already run on this hardware and are much more advanced graphically than say...Tetris. Unfortunately most are not free or open source.

My point is basically this:
You don't want 6/10 downloads to be people that wind up not even playing. Why? Because it will save everybody bandwidth. A lot of people looking for free games to download don't have the $ for new hardware or they'd also have the cash to go buy a game and would never even look for this one.

I understand that the requirements are changing, but surely you know that/if it won't run on a Pentium II with 128MB of ram and can at least give a ballpark amount of the space the game will take on the hard drive.
