Every Steam game lags!

Yes, every game in my Steam Library lags.
The games are..

Bastion
Terraria
Alien Zombie Megadeath

I fixed Terraria by setting the Multi-GPU/Mixed GPU option in Nvidia Control Panel to Compatible. The rest still lags, it's sometimes fixed by being in the game for a while, or changing the resolution back and forth.

So I also have Farcry 2, which is not in Steam, and that runs perfect. I also tried to uninstall-reinstall Steam with the games, didn't work either.

Any ideas?

Hey Mickey!

Nice tip, but it didn't work.

Any other ideas?

Fred,
Is you card on the low end and have you turned down the resolution?

I did a search, the box in upper right corner, for Steam lagging, so while help is coming you might want to
check some of those posts out.

I don't have any Steam games (or even a Steam account), so I can't help you with specifics. However, here are a couple of questions that might help others.

1. Have you always had this problem, or has it just happened recently?
2. If only recently, did it first occur last week when the Steam servers were hacked?

If both answers are affirmative (yes), then it could well be that Steam itself is still in the process of sorting their servers out and, due to the reduced capacity available, it is inevitable that more lag than is desirable will be present (some lag will always be present). If this is the case, then you should find an improvement in performance (and a reduction in lag) once Steam have finished their maintenance.
