Setting Windows Power Plan to "High Performance" to ensure the CPU/iGPU isn't throttling.

Many laptops allow changing the pre-allocated video memory directly in the BIOS under "DVMT" or "UMA Frame Buffer Size".
Dedicated Video RAM (VRAM) is the lifeblood of modern PC gaming and graphic-intensive applications. When your system lacks enough physical VRAM, games stutter, frame rates drop, or titles refuse to launch entirely. For gamers running integrated graphics—such as Intel HD, UHD, or Iris Xe graphics—VRAM limitations are a constant hurdle. phdgd virtual vram tool
PHDGD stands for . For years, this developer group created modded drivers to squeeze extra performance out of Intel integrated graphics.
The tool adds or modifies keys like IncreaseFixedSegment or DedicatedSegmentSize within HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\4d36e968-e325-11ce-bfc1-08002be10318\0000\GMM . a game into starting, it doesn't physically add hardware
By defining a higher static baseline for memory allocation via registry tweaks, it can sometimes prevent sudden game crashes associated with aggressive dynamic memory shifting. Risks, Drawbacks, and Safety Concerns
: When a game asks, "How much VRAM do you have?", Windows points to this registry value instead of the hardware's actual zero-sum dedicated memory. Important Considerations I need help with my VRAM - HP Support Community - 7236143 Intel Iris Pro Graphics 5200 Intel Iris Graphics
To get the most out of your setup, I can provide additional optimization strategies. Let me know if you want to know how to without a tool, how to verify if your RAM is running in dual-channel , or how to optimize Windows for low-spec gaming . Share public link
