How can I find out which graphics card I have in my PC?

SketchUp is a graphics-heavy program. Knowing your graphics card can help you troubleshoot odd visual behaviors or recommend a good-performing card to other users. The easiest way to find your graphics card is to run the DirectX Diagnostic Tool:

1. Click Start.
2. On the Start menu, click Run.
   
3. In the Open box, type "dxdiag" (without the quotation marks), and then click OK.
4. The DirectX Diagnostic Tool opens. Click the Display tab.
   
5. On the Display tab, information about your graphics card is shown in the Devicesection. You can see the name of your card, as well as how much video memory it has.

                                        Another process

Go to the windows start button (bottom left of your screen), click it and then select 'control panel' from the menu that pops up. You then need to find the 'display' control panel. If you can't see it, you need to go to the top right of this new window and change the 'View by:' to show 'large icons'. Then you will find it.

Then you need to click on 'change display settings' on the left hand side:

Then select 'advanced settings at the bottom right corner:

You then have a window that shows something like this. In my case, it my video card is an ATI radeon 5700 series. This is the information you need to know, in order to get your video card drivers. The company is likely to be ATI, nvidia or intel, or possibly another less-well known one.

You then need to go to their website and download the FREE drivers. Here are links to the main manufacturers. You are looking for a link that says 'drivers' or 'support and drivers'.

                                For Xp :

For Windows XP: 
There are three steps to updating your video card drivers. Don't worry, its quick and easy. Here goes:

STEP ONE - What Video card do you have?

Presuming you have Windows XP, the quickest way is to right click your windows desktop (wallpaper) and select 'properties' from the drop down menu that appears. A window like this will open:

This is the 'Display control panel' for Windows (its similar for windows 98, me and 95). You want to select the 'settings' tab at the top right of this window...

Now click the button marked 'advanced' at the bottom right...

Ok this window (above) may have a different number of tabs on your PC, click the 'adaptor' tab

Here at the top where it says 'adaptor type', is your video card. In my case, it's a NVIDIA GeForce 6800 GT. Make a note of this.
