So just making sure, my computer can play KOTOR? These are the requirements from Steam:
PC System Requirements OS: Windows XP and Windows Vista Processor: Intel Pentium 3 1Ghz or AMD Athlon 1GHz Memory: 256 RAM Graphics: 32 MB with Hardware T&L DirectX®: Directx 9.0b or better Hard Drive: 3.5 GB Sound: Directx 9.0b compatible
Though a fight every now and then makes life a little more interesting, don't ya think?
Your laptop is dated and wasnt very powerful to begin with. But you can play old games just fine. Games from 2007 and older will run on med to high settings without much problems. That includes pc games from the ps2 era and a few from the ps3 era as well.
Oblivion (2007) is probably the most demanding game you will be able to play at high settings. For newer games you will have to lower the settings (disable shadows, lower resolution, decrease draw distance, etc) to achieve playable frame rates.
Some games are better coded than others or require less resources, so its possible a few more recent games will run fine . For example Crysis (2007) require FAR more resources than Mount and Blade (2010), which means crysis will run on very low settings and Mount and Blade on med despite the latter being newer.
But for post-2007 games youre taking a gamble or forced to lower settings.
