Nvidia 7800GS is a very old GPU and Windows XP is just as old. I am surprised you still use it to be honest.

Anyway, are you sure you have installed correct drivers? For this particular GPU you might want to install this:

If you already have this installed, check if your PC has the latest DirectX driver:

Then re-run SETUP again and check if Tomb Raider recognizes your GPU. If you still have lags, then:

1. Click on Start Menu and click on 'Run' icon. Alternatively click Windows logo + R on your keyboard.
2. Type dxdiag and click enter.
3. Wait until it loads, then click "save all informations" and save file.
4. After that post here everything there is inside that file.
