Portal 2 refuses to launch on PC.

AceFront · 04-26-2012, 01:53 PM

Okay, I am having a problem launching Portal 2 recently. I've never in all my time owning the game have had this problem, but it's getting -QUITE- annoying.

So this is it: whenever I go to launch the game, it will go through the standard "Preparing to launch ____" procedure, but then it goes away REALLY fast, and the Steam client stays on screen, and the resolution dosen't go down to 1280x720. In fact, nothing happens. It says I'm "In Game" for about 10 seconds, then my screen moves for a split second, and it says I'm just "Online".

I've already tried BOTH Defragmentation of Cache Files, Verifying the Integrity of Cache Files, and even un-installing and re-installing the game. I have installed no mods on Portal 2, and have never had this problem on this or my other, much worse, computer in the past.

Any explanation?

Try setting -autoconfig in Properties > Launch Options. This will ignore any changes to settings you have applied, possibly bypassing the issue.

Unfortunately, no dice. It did the same thing.

Also, computer specs?

AceFront · 04-26-2012, 04:17 PM

CPU: AMD A6 3400M Quad-Core Processor
GPU: AMD Radeon HD 6520G
4 GB DDR3 RAM (Plan on upgrading that to 8)
OS: Windows 7

It's a laptop, so nothing amazing, but if you need anything else, I'll tell.

I got my son Portal 2 and so we wanted to do some co-op. I tried to load it up, and same thing. Says it is launching, acts like it will, then nothing at all. I have tried defrag, uninstall and reinstall. Latest AMD drivers.

It's not like my computer is old:

CPU i7-950
12 GB DDR3 RAM
AMD 6970 GPU

The only thing I can imagine is a recent Steam update?

Or maybe a recent windows update? When I get sudden strange issues I check the system restore points to see if one has been created recently due to an update. Sometimes they can go a bit wrong and restoring fixes it. The update will get applied again and chances are there won't be any problems that time around.

I will have to check. I know I have tried a few drivers to no avail. Running Win 7 Ultimate 64-bit and have tried it as an administrator and normal. It is perplexing as heck as my son finished Portal, bought Portal and wants to play co-op and I am out of luck on my beast of a rig.

AceFront · 05-08-2012, 01:29 PM

Actually, I have 13 Windows 7 updates, so I'll just install those and see if anything's wrong.

EDIT: Still not working. I've tried so many times, it's ridiculous.

Same problem here, after last update. Work without problem before patch. X6 1055, 16GB, 6870 1GB, Win 7 64bit

cortez09 · 05-08-2012, 03:21 PM

Same with me i got an i5 750, 4gb ,5770hd

it seems most of us here have AMD GPUs so it might have to do with its drivers

jugularis · 05-08-2012, 03:57 PM

Can someone from Valve take a look on this issue? Hammer now works, but game itself not. Other Source games without problem. Only P2 after this update. It redownload one 20MB file after each cache verification. It is funny, that my second computer with intel crap gpu (G860 based)works without any problem.

IT DOES THE SAME THING FOR ME.

Nothing happens after. If a support mod. at Valve is reading this, please. PLEASE consider fixing this.

I don't own Portal 2, but maybe it's an AMD issue? I read the specs and all of them have AMD config (CPU and/or GPU). Maybe the AMD dual-core driver needs an update or something?
Sadly I never used AMD. Just Intel/nVidia a decade.
