The graphics memory of my notebook is 2.5 GB , 1 GB dedicated memory. After installing Ubuntu 12.04, I activated the graphics card from Applications->additional drivers. I have dual boot, all high end games are working fine without any issues in Windows 7 but games are very slow in Ubuntu.

The games that I have installed in Ubuntu are Warzone2100, 0AD, ManiaDrive and Scorched 3D. All the games are playing but very slow response and poor graphics. I have seen the gameplay videos of these games, they are good esp Warzone2100 and 0AD.

My Questions:

  1. How to check the graphics memory ?
  2. Why the games respond very slow ? Please provide the solution to improve it.

I love using Ubuntu but for games I depend on Windows 7.. I do not expect to run high end graphics games in Ubuntu but I would like to play Warzone and 0AD without any problem. Help me.

To check your graphics memory you can install hard info, it should be under PCI devices. with regards to games running slow, it seems to be quite common in ubuntu, I checked in https://wiki.ubuntu.com/HardwareSupportComponentsVideoCardsAti and your video card is not offically supported, not yet anyway, that doesn't mean it can't work well, though. I assume that you installed the proprietry drivers, if you didn't you should. here's some info on ways to do that: https://help.ubuntu.com/community/BinaryDriverHowto/ATI
