Surfer's system requirements are listed below.

Minimum Requirements:

• Windows 7, 8 (excluding RT), 10, 11 or higher
• 32-bit and 64-bit operation system support
• 1024x768 or higher monitor resolution with minimum 16-bit color depth
• At least 500 MB free hard disk space
• At least 512 MB RAM

Optimal Settings

• Gridding, contouring, and color relief operations, all of which are heavily computational, are processor reliant and are multi-threaded.  In Surfer, you will find a setting at File | Options | General | Max number of processors to use.  It should be set to use all cores.
• For gridding and contouring operations, CPU performance is important.  The more cores the better. 
• When working consistently with very large data files, more RAM is important.
• ​Turning off auto recovery can help performance in some cases.  It is OFF by default, but it can be enabled at File | Options | General | Save auto recovery information.
