Product: EliteBook 820 G3
Operating System: Microsoft Windows 10 (64-bit)

Hi,

 

I am an experienced software developer specialized in graphics programming. My applications do need to run on lower-end Intel HD graphics hardware.

I currently own two computers:

 

- a late 2015 desktop computer with a i7-6700 processor (with Intel HD 530 graphics)
- a 2016 EliteBook 820 G3 laptop computer with a i5-6300U processor (with Intel HD 520 graphics)

 

Both computers have 16GB of central memory and both have the latest Intel HD driver, as well as the latest system BIOS. The laptop has the latest may 2021 BIOS (N75 v1.52).

 

On the desktop computer, when I use an OpenGL application allocating 260MB of video memory, things succeed and run fine.
On the laptop computer, even though my BIOS setting is "Video memory size: 512 MB", the same application fails to run, reporting that the maximum size of an OpenGL memory allocation is 128MB.


I wrote a program to check things, and the maximum memory block size reported by OpenGL indeed is 128MB, which is just insanely low, and does not match my BIOS setting anyway. The same program reports plenty of graphics memory on my desktop computer.

 

It is suggested that the BIOS of the laptop may be doing something wrong. What can I do to solve the problem? This is critical for me.

 

Thanks for your help.
