Performance issues on desktop 

If you have struggled to perform tasks in VXT, like answering calls, losing inbound or outbound audio, your device may be experiencing performance issues.

⚠️ This article concerns the VXT desktop app on the Windows operating system. ⚠️

What's going wrong?

Whenever we are facing an issue we should try to determine the most likely underlying cause of the issue first and then test possible solutions. 

If VXT is slow to respond, frozen or you are experiencing strange audio behaviour e.g. periods where you can't hear the caller but they can hear you or vice versa for say 30 seconds, performance issues may be the cause.

Performance issues occur when device's CPU and/or Memory cannot handle the load required by the programs you are using e.g. your computer has 16GB of Memory but your programs are asking it for 18GB.

It is very quick and easy to test if you might be having performance issues.

Testing for performance issues

First, press Ctrl + Shift + Escape to open 'Task Manager'.

Once we've opened Task Manager, we should see a list of all of the programs running on our device and next to each program, their respective resource use which will update every few seconds. This is useful to see which programs are consuming the most CPU/Memory resources.

Lets check how much memory you have and what is being consumed.
Click on the performance tab in the left pane and then click on Memory:

In this screenshot, we can see that 87% of memory is being used out of 8GB.

To understand what we are seeing we can use a rule of thumb.

💡 Performance issues occur when Memory and/or CPU are regularly above 75%. 

In the example screenshot above we see can that Memory utilization is at 91% and at the same time our device was regularly unresponsive.

Both of the example screenshots above indicate that memory utilization is the problem.

How to solve performance issues

To help manage resource utilization we need to consider the following,

  • Restart your device daily. 
  • Always close apps and background processes when they are not in use unless they are essential to your business.
  • Avoid leaving an excessive amount of browser tabs open.
  • Consider upgrading your device to include a more powerful CPU and or a greater amount of Memory that meets the minimum specifications outlined in the Computer Recommendations section below. 👇

If you have performed the above steps and your Memory and/or CPU are always below 75% and issues persist, contact VXT Support. 

Computer recommendations

For someone in a professional role that involves using a lot of different applications on the computer at once such as an attorney, consultant or accountant, a computer should reach the following minimum specifications:

  • Memory ⚠️
    Windows devices: Minimum 16GB of RAM (Random-access memory)
    Apple devices: Minimum 8GB of RAM (Random-access memory)

  • CPU ⚠️ 
    A modern Intel i5 dual-core, Apple M1 processors, or equivalent, initially released no earlier than the last few years.

  • Operating system
    64-bit version of Windows 10 / Windows 11 or macOS 10.14+

  • Internet browser
    Google Chrome (the most recent version)

Comment from VXT on November 30, 2025: We are aware customers who have recently updated to Windows 11 are experiencing an increased rate of performance issues.
