Checklist for performance issues in Pythagoras

Use this checklist when Pythagoras responds slowly, takes long to recalculate, or shows unexpected performance issues. You may note the requested information or simply send screenshots to support.

STEPS

1. Check your Pythagoras version

1. Open Pythagoras.

2. Go to Help > About Pythagoras.

3. Note the full version number.

4. Check whether you are using 32-bit or 64-bit (if mentioned).

Important: always provide the complete version number, for example 25.04.01. Not just ‘version 25’.

2. Check where your project file is stored

1. Open the folder where your project file is saved.

2. Check whether the file is located on:

   • A local drive (for example C:)

   • A network drive or server

Working over a network may cause delays when opening, saving or recalculating.

3. Check your processor (CPU)

1. Press Ctrl + Shift + Esc to open Task Manager.

2. Go to Performance.

3. Click CPU.

4. Note the processor type and model or take a screenshot.

4. Check your memory (RAM)

1. Open Task Manager.

2. Go to Performance > Memory.

3. Note or screenshot:

   • Total RAM

   • Current usage while Pythagoras is slow

5. Check your graphics card (GPU) and driver

Graphics performance directly affects Pythagoras, especially in 2D and 3D views. On some systems, Pythagoras may run on the integrated GPU instead of the dedicated GPU, which impacts performance.

A. Check the graphics card (GPU)

1. Open Task Manager (Ctrl + Shift + Esc).

2. Go to Performance > GPU.

3. Check whether multiple GPUs are listed (for example GPU 0 and GPU 1).

4. Note or screenshot:

   • The exact model of each GPU

   • Which GPU is active while Pythagoras is running

Or:

1. Open Device Manager.

2. Go to Display adapters.

3. Check which graphics cards are listed.

Important: many laptops have two GPUs (integrated and dedicated). Mention both if applicable.

B. Check the graphics driver

1. Open Device Manager.

2. Go to Display adapters.

3. Right-click the graphics card and select Properties.

4. Open the Driver tab.

5. Note or screenshot:

   • Driver version

   • Driver date

An outdated or incorrect driver may cause performance or display issues.

6. Check your Windows version

1. Press Windows key + R.

2. Type winver.

3. Press Enter.

4. Note or screenshot:

   • Windows version

   • Build number

7. Check system load

1. Open Task Manager while the slowdown occurs.

2. Check the usage of:

   • CPU

   • Memory

   • GPU

   • Disk

Preferably send a screenshot while the issue is occurring.

RESULT

You have collected all relevant system and version details. With this information, support can determine whether the issue is software-, hardware-, driver-, or network-related.
