The graphics card is the most determining piece of hardware of your system when it comes to impacting your overall PC performance. If your graphics card (dedicated or integrated) is old with mediocre specs, you’ll most likely have some trouble with the sophisticated graphics in cove.tool. Instead of buying a new GPU, you can increase performance by increasing your VRAM. Often this is set very low and needs a boost. This works on computers with integrated graphics cards.

What is VRAM?

Most of the errors generated by a lacking graphics card have something to do with the video RAM (VRAM). VRAM is a special type of RAM that is responsible for holding on to information that the GPU needs. It enhances performance by allowing the GPU to fetch info and beam it to your monitor in a hasty matter.

How to Increase the Dedicated VRAM of your GPU

If your dedicated GPU is outdated or you’re still relying on your integrated graphics card on an old laptop, upgrading to a new GPU model will give a huge boost to the overall performance (if you have CPU and RAM good enough to sustain the growth).

There are two other ways that you can use to increase the dedicated VRAM of your GPU. Feel free to follow whichever method seems more approachable considering your particular situation.

How to check the amount of video RAM

Before you begin the process of doing a VRAM increase, it’s important that you don’t lose track of the real count. Here’s a quick guide on seeing the amount of video RAM (VRAM) that you have on your computer.

Note: The steps below were created with Windows 10 in mind but you’ll most likely be able to recreate them on older Windows versions. For additional help, refer to the Note paragraphs under each step.

  1. Press Windows key + R to open up a Run box. Then, type “ms-settings:easeofaccess-display” and hit Enter to open the Display tab of the Settings app.


​ Note: For Windows 7 and Windows 8, replace the command above with dpiscaling and hit Enter.

2. Scroll down and click on Advanced display settings, then click on Display adapter properties for Display 1.

3. You can check out your VRAM count under Adapter information at Dedicated Video Memory. But keep in mind that if you have both a dedicated GPU and an integrated graphics card, this window will show you the integrated solution if your PC is in idle.

Note: If you’re dedicated GPU is idle, you can force your system to switch to it by performing a stressful activity. Also, you can access your dedicated GPU utility (e.g. NVIDIA Control Panel) and see the dedicated Video Memory from there.

Method 1: Increasing Dedicated VRAM from BIOS

The first and the most recommended make-do solution is to adjust the VRAM allocation from your computer BIOS. Sure, this method is not applicable on all motherboards, but most manufacturers include an option tweak the VRAM allocation.

Here’s a quick guide on increasing the dedicated VRAM from the BIOS settings:

  1. Restart your computer and enter the BIOS settings at the next startup by pressing the dedicated BIOS key repeatedly during the bootup. Try pressing F2, F5, F8 or Del key repeatedly. If that doesn’t work, search online for specific steps on entering the BIOS settings in relation to your motherboard manufacturer.

  2. Once you reach the BIOS menu, look for a menu similar to Graphics Settings, Video Settings or VGA Share Memory Size. You can typically find it under the Advanced menu.

  3. Then, up the Pre-Allocated VRAM to whichever option suits you best.

4. Save the configuration and restart your computer. At the next startup, use the procedure above to see if the VRAM count has been increased.

If this method wasn’t applicable or you’re looking for a different approach that doesn’t involve altering BIOS settings, continue down to Method 2.

Method 2: Increasing the Dedicated VRAM via Registry Editor

Keep in mind that for most integrated graphics cards, the amount of VRAM reported in the Adapter Properties window is completely irrelevant for the actual performance since the system will automatically adjust it on an on-demand basis.

However, WebGL (the 3D environment in cove.tool web-app) will not allow you to run them if you are under the minimum specified VRAM. In this case, you can use a Registry Editor trick to modify the values so that the game will no longer encounter the error. Here’s a quick guide on how to this:

Note: Keep in mind that the following steps are only applicable for integrated GPUs from Intel.

  1. Press Windows key + R to open up a Run box. Then, type “regedit” and hit Enter to open Registry Editor.

2. Inside Registry Editor, use the left-hand pane to navigate to the following location:
​HKEY_LOCAL_MACHINE \ Software \ Intel

3. Right-click on the Intel key and choose New > Key and name it GMM.

4. With the GMM key selected, move over to the right pane and select New > Dword (32-bit) Value and name it DedicatedSegmentSize.

5. Double-click on DedicatedSegmentSize, set the Base to Decimal and insert a value from 0 to 1024. This value will be the amount of VRAM displayed inside the Adapter Properties menu. If you have 16 GB of RAM, 1024 MB is good. Otherwise go with 512 MB for the VRAM.

6. Save the changes and restart your computer to enforce the changes. At the next startup, see if you can start cove.tool without the error.
