More VRAM Allocation? Model Number: A15-41M Part Number: NX.KTPAA.001

I just purchased an Aspire A15-41M Ryzen™ 5, 8640HS with 760M iGPU and upgraded to 16GB of DDR5 ram via an 8GB stick. The Readon software allocates 2GB though the use of changing the tuning menu from "Productivity" (512MB) to "Gaming" (2GB). I've confirmed this through CPU-Z. However, is there a way to allocate 4GB to VRAM? I've updated both the Raedon Software, video drive and BIOS (1.08) to the latest but I still see no options to change any of these setting.

Is there any way to change this manually or trick it somehow to allocating 4GB? Please help…

    On your Aspire A15-41M with a Ryzen™ 5 8640HS and Radeon 760M iGPU, the amount of VRAM allocated to the integrated GPU is mostly controlled by the system BIOS and sometimes managed dynamically by the OS, but manual adjustment options are limited.

    Some systems allow you to allocate more VRAM through BIOS settings. Not all Acer BIOS expose this option, especially on budget or slim models.

    The laptop also uses Dynamic Memory sharing both Windows + AMD drivers often use dynamic memory allocation, where more system RAM is assigned to the GPU when needed up to a point. So even if it shows 2GB "dedicated", it may borrow more from RAM as needed, depending on the workload.

    The bottom line. Only if your BIOS has an option to increase it. I doubt for this model has that option in BIOS. Your iGPU may still use shared memory beyond 2GB if the app/game requires it, though not all software will recognize it as dedicated VRAM.

    Thank you that makes sense however, I'm trying to run Doom Eternal and I keep getting an error like below? It loads through a few opening screens but never makes it to a menu screen. I keep running into the error below. Does this mean its allocated 7GB? Should be more than enough VRAM no?

    Try to force the Game to Use Dedicated GPU (AMD). Windows sometimes defaults to integrated Vega graphics instead of the RX GPU.
    Right-click Desktop → AMD Radeon Settings. Go to Graphics → Graphics Profile → Set to "Gaming" or "eSports". Under "Game Graphics", add Doom Eternal’s .exe and set:
    GPU Workload → "Graphics". Performance Tuning → "Manual" increase power limit if possible.
    Save & Restart the game.

    Also, Lower In-Game Settings (Critical for Low VRAM)
    Launch Doom Eternal → Settings → Video. Apply these optimizations: Resolution: 1280×720 (720p)
    Texture Quality: Low, Shadow Quality: Low, Dynamic Resolution Scaling: On
    Disable: Motion Blur, Depth of Field, Chromatic Aberration
    Restart the game after applying.
