Custom Resolution Utility (CRU) allows you to manually change your monitor’s FreeSync range, quick and easy.
Changing your monitor’s variable refresh rate (VRR) range can sometimes greatly improve the performance in video games. Luckily, the process is very quick and simple!
To increase or decrease your monitor’s FreeSync range, you’ll need to download a free application called Custom Resolution Utility. You can do so here – a forum post by the creator of the application.
There are two different methods to edit the FreeSync range, depending on whether you’re using DisplayPort or HDMI.
Here’s how to edit the FreeSync range if you’re using DisplayPort.
Once you download and unpack the files from the link above, run CRU.exe.
In the drop-down menu at the top of the window, select your monitor. It should be labeled as (active).
Then, next to your monitor’s model name, click on ‘Edit.’
A new window will appear called ‘Display Properties.’ Here, you can change the VRR range – just type in the number you want under ‘Range limits’ in the box next to ‘V rate,’ and then click ‘OK.’
You can then click ‘OK’ in the CRU window too.
Next, run the restart64.exe file which will reset your graphics driver and apply the changes.
Your monitor will go blank a few times.
If you’ve accidentally typed in a frequency that’s not supported by the monitor, and the picture doesn’t come back in 15 seconds, just press ‘F8’ to revert the changes.
You can repeat the process when you want to change the VRR range again.
Keep in mind that you won’t be able to increase the range on some monitors, similar to how overclocking works.
One monitor with a 40-75Hz range might works flawlessly if you increase its range to 30-75Hz, but another unit of the same display may not even support 39-75Hz.
If you’re using FreeSync over HDMI, you’ll have to edit the extension block instead.
In the ‘Extension Block’ window, select ‘FreeSync range’, and then click ‘Edit’.
Type in the range you want to set and click ‘OK’ on all three windows.
Run the restart64.exe file and you’re done.
