    Can you undo changes to VRAM using regedit


    Hey guysSo I wanted to dedicate some of my RAM to VRAM to enhance game performance, so I watched a video from youtube that made me create a GMM file in the intel part of HKEY_LOCAL_MACHINE-SOFTWARE-Intel. Then I added a new key called GMM and created a DWORD called "dedicatedsegmentsize". It however caused my Laptop to slow down drastically after reboot because the RAM was cut in half. I thought deleting the file would help undo it but that fail. If anyone knows of a solution, PLEASE HELP.

    :)

    Increase VRAM

    My laptop comes with 128mgb of VRAM, which means it cant support most games that need more vram. I upgraded it to 512 VRAM using the regedit technique: is there any way to make it higher than that?

    Is it really possible to change default VRAM of GPU?

    A Registry patch fix exists for Intel GPUs, but not for AMD.

    I have not tried it (probably because Frogger is too high tech for me) but you can find it at https://www.thewindowsclub.com/increase-dedicated-video-ram-windows-10 which states in part:

    I'd suggest testing performance in-game before and after to make sure this change is beneficial.

    --

    Follow the below steps to reallocate RAM as VRAM for integrated Intel graphics cards.

    Open Run and type regedit then navigate to the following path:

    HKEY_LOCAL_MACHINE\Software\Intel

    Right-click on the Intel folder. Choose New and click on Key. Name the key as GMM.

    Select the new GMM folder on the left sidebar.

    Right click on the right side of the Window and click on New from the drop-down menu.

    Increase dedicated Video RAM in Windows 10

    Choose the Dword (32-bit) and name it as DedicatedSegmentSize .

    Double click on the DedicatedSegmentSize and click on the radio button with option Decimal to set the base to Decimal.

    Enter the number of megabytes of RAM you want to allocate as VRAM in value data. Make sure you type a number within the range from 0 to 512.

    Save to apply the changes.

    Restart the system.
