We recommend getting the latest versions of graphics card drivers directly from the hardware vendors NVIDIA, AMD and Intel.

Computers with two graphics card are becomming increasingly common. For running the advanced visualization techniques in Geocap it is crucial to use the high performance card. Sometimes we must explicitly select which graphics cards should be used by Geocap.

Please note that running Geocap on battery power may force the low performance graphics card to be used by the computer.

Check which graphics card Geocap is using:

Click Shell and Workspace in the Toolbox.
Type in: lod glreport in the shell and press enter.
Go to View > Messages
In the new dialog that pops up you should be able to see which graphics card Geocap is using. i.e
```
GL Version:4.2.0
GL Vendor:NVIDIA Corporation
GL Renderer:Quadro 2000M/PCIe/SSE2
```
