If you want to manually set these settings yourself, I’ve kept those instructions below.

How to Manually Increase Frames Per Second with Cryoutilities

Change the Swap File

In the Swap tab, you will want to first set a new swap file size.

By default, the swap file is set to 1GB. You can change the swap file size between 1 GB and 32 GB. 16 GB is the recommended file size.

Give it a few minutes after successfully changing the swap file size.

Specify the swap tendency

Next, you will want to use the app to update the swap tendency or swappiness. While the figure is 100 by default, you can set it to 1 or 50 to make your Deck balance between using the installed RAM or swap file.

cryoutilities 2 swappiness

Keep in mind that for as long as the swap tendency is low, the Deck will prefer the RAM over the swap. Using the RAM will be faster, but you will get more flexibility when you use SWAP.

Enable Memory Options

Next, go over to the Memory tab in the app and click on the enable button for each of the options:

  • Enable Huge Pages
  • Enable Shared Memory in THP
  • Set Compaction Proactiveness
  • Enable Huge Page Defragmentation
  • Set Page Lock Unfairness

Increase The UMA Frame Buffer Size To 4

Now, increase the UMA frame buffer size to 4 from the default 1GB. To do this, press and hold power and up volume button while the Deck is off to access the Deck’s BIOS.

While in the BIOS, select “Setup Utility, and click “Advanced.” Change the 1GB to 4GB and save the setting.

Other Ways to Increase Frame Rate in Games on the Steam Deck

Using CryoUtilities above is the most effective way to get more frames out of your game, but there are a few settings in the Steam Deck performance overlay that can also help you out if you set the performance overlay level to the Advanced view.

Click here to read our complete guide on the Steam Deck performance overlay.

Some of the settings you can quickly look to change are:

  • Turn half rate shading on.
  • Turn your framerate limit up.
  • Turn the thermal power limit up (will decrease battery life)
  • Turn the GPU clock frequency up (again, worse battery life)
  • Turn your scaling filter to FSR

Playing around with these performance metrics can have a large impact on your frame rate, better battery life, power consumption, GPU usage, and more.

Make sure that you don’t have your FPS limiter turned on, which will prevent you from getting a high FPS no matter what other settings, swap files, and trim you set.

How Does CryoUtilities Work?

Without being too technical, CryoUtilities allows you to adjust your Steam Deck to efficiently use the memory in its solid-state drive (SSD) and RAM for enhanced performance. A description on each of the things you can change is below.

You can quickly reverse any changes you have made through CryoUtilities should the mod make you feel skittish.

Short Term vs Long Term RAM

Long-term memory is stored on solid-state drives or SSD. The Deck has an SSD between 64 GB and 512 GB.

Compared to short-term memory, long-term memory holds a lot of data indefinitely. The type of data stored is endless. You can keep anything that you want to stay for a long time.

On the other hand, short-term memory is stored in various stages of RAM. RAM is generally very fast but has low capacity and loses content when it doesn’t get power. It holds a small amount of data or information for as little as twenty seconds.

Swap File

This system file creates temporary storage on the hard disk or solid-state drive, mainly when your Deck runs low on memory. With a swap file in place, your Deck can use more memory than is physically installed. This means that your Deck can run more games with the installed RAM until you can introduce a more permanent solution, like a RAM upgrade.

Swap Tendency

Swap tendency is also known as swappiness. It is how eager the system puts the data in the swap instead of the random access memory (RAM) on a scale of zero to 100.

The higher the swappiness, the more the system puts more data in the swap and vice versa. By default, the Steam Deck comes with a swappiness of 100.

By turning this number down, you can force the Deck to use up its available RAM space before going to use virtual space.

TRIM is a command the operating system uses to notify the SSD of the page or pages in a specific block to be erased when not in use. Erasing a page or pages in a block allows the SSD’s controller to better manage the available storage space.

In other words, without TRIM, data is loaded into the cache. With TRIM, all data in the block will be moved to the cache.

What is VRAM?

VRAM is an acronym for video random access memory. It refers to any RAM used to store image data for the Deck to display.

VRAM is a buffer between the display and the Deck’s processor. It is often called the frame buffer. The primary purpose of VRAM is to ensure the smooth and even implementation of graphics display on the Deck.

Before images get to the display, the processor will read them as data from non-video RAM and then immediately write them to VRAM. The data is sent as a digital signal from VRAM through a port to the Deck’s display.

What are Huge Pages?

Huge Pages are a new feature in Cryoutilities. It allows the kernel of the Steam Deck to save templated information about your game in a central location so that it doesn’t need to continuously load the information each time.

What is Shared Memory?

Shared Memory in transparent Huge Pages tells the Linux kernel to store information in huge pages if it is efficient to do so.

What is Compaction Proactiveness?

Compaction is a process where the Steam Deck will rearrange its data blocks for efficiency. Normally this is a good thing, but it can cause memory spikes.

We choose to disable this so that your Deck doesn’t rearrange memory while you are playing.

What is Huge Page Defragmentation?

Similar to Compaction, the Deck will rearrange data in the huge block while you play. By disabling this, you will see less frame rate drops.

What is Page Lock Unfairness?

Steam Deck processes which are more memory intensive tend to take and use Huge Pages more frequently. This can prevent other processes from getting their chance to write to the page.

If you decrease your Page Lock Unfairness, then the kernel on the Deck won’t stall out as much and you will reduce stutter in games.

How to Increase the VRAM on the Steam Deck

We already mentioned that by default, the Steam Deck has a 1GB GPU. However, you can upgrade the GPU up to 4GB by getting into the BIOS of the Deck.

Follow this step to increase the VRAM on the Steam Deck:

  1. Completely shut down the Steam Deck. You can shut down the Deck through the power button.
  2. Press and hold the power button and the volume up button until you hear a beep sound from the Deck before releasing the buttons.
  3. Wait a few seconds, and you should see a screen with large buttons.
  4. Click on the Setup utility button and navigate to where you can change the UMA frame buffer size from 1 GB to 4 GB.
  5. Press the Steam Deck select button and press yes to save and exit.
  6. It will immediately reboot, and you are good to go.

Performance and Battery Life

By default, higher settings in your performance menu will lead to a decrease in your battery life. This is true for most games, but especially those AAA titles that use more power.

In order to increase frames per second, you need to either decrease your settings or else optimize how the Steam Deck uses its memory. Using CryoUtilities above will help you get more performance with less power consumption.

Pay attention to your battery icon to get a feel for how fast you are draining your battery life.
