I installed Osmos the other day on an older PC.

I started the game and it lags so much that I dont even get to see the menu screen.

Any ideas as to why this is happening?

The PC specs are as follows:

  • CPU: AMD Dual Core 3800+
  • GFX Card: ATI X1600
  • OS: Win7 Professional
  • RAM: 3Gb

Well, I'm afraid it's pretty easy. The video card you're using is quite old, and it doesn't support Windows 7. Seeing as Osmos is a relatively new game, it's going to be slow.

You could try updating drivers, but seeing as ATI doesn't support Windows 7 for that card, it might or might not be successful.

  • I figured that. PC technology moves too quickly.

I had this issue, and my machine is fairly new.

In the FAQ, they explain that this can happen if your video drivers don't support transparency/alpha-blending well.

I had assumed that since Windows 7 included video drivers in the automatic updates, I was all set, but I needed to install new drivers to even get to the menu. After updating, it runs smooth as silk.

    I downloaded a new driver that I hope is going to work for this. But I am not holding my breath Jul 13, 2010 at 11:53

It runs almost smoothly on my 750 MHz Notebook with an ATI Rage on WinXP, so I guess Win7 is the problem.

However, you could use a small Linux Distro with a current wine, Osmos runs great on my Athlon XP 1800+ with ATI Mobility Radeon 9200 under Ubuntu 8.04. Just remember to reinstall OpenAL for Osmos to run. If you don't want to bother with partitioning I recommend using wubi, which installs Ubuntu as an image file on your NTFS partition.

  • Thank you. I will give this a try if the new driver doesnt work. Jul 13, 2010 at 11:57

Cant exactly remember how I came about the link, but over here is a driver that I downloaded and installed.

I tried running Osmos again and it works like a charm.
