The release notes for build 1771977793 state...

Hardware Survey / System Information

• Fixed an issue where VRAM on some graphics cards was not reported correctly (-1)
• In the case of multiple display adapters, we now select the one with the most VRAM to display and report to Steam

As I cannot trigger a Hardware Survey, I ran System Info (from within Help menu) and noticed that my iGPU was reported and not my dGPU with 8GB VRAM.

Steps for reproducing this issue:

1. Update Linux Steam Client to build 1771977793
2. Run Help => System Info
3. Note the iGPU with little VRAM is reported, and not the dGPU with 8GB VRAM

querying /sys manually myself I find the following...

iGPU... 512MB
cat /sys/class/drm/card2/device/mem_info_vram_total
536870912

dGPU... 8GB
cat /sys/class/drm/card1/device/mem_info_vram_total
8573157376

In System Info it reported the iGPU (Primary) correctly with 512MB VRAM (equalling /sys)... The issue/solution lies with how the GPUTopology query found an iGPU vram_size_bytes = 11287379968 ... of course 11GB > 8GB ... except 11 GB on the iGPU is an error

[DanielR-I]

in case it helps... glxinfo also reports correct VRAM values

Hello @DanielR-I, Steam's System Information is telling you the GPU the Steam client is running on. Integrated graphics do not have dedicated video memory, instead, a relatively small section of system ram is set aside for dedicated GPU use (in this case 512MB), and the rest of the video driver's needs are shared with the rest of the system as regular system ram.

The details listed in Steam's System Information has no effect on what's available to games and does not restrict any game's access to your discrete video card.

[DanielR-I]

@kisak-valve So was it an error in the release notes to say that "System Information" (in addition to Hardware Survey) were now going to report the GPU with the highest VRAM?

And is it not an issue that the steam GPUTopology query (noted in my second post) thinks the iGPU has 11GB VRAM? That for sure is incorrect data that will fail logic during the next Hardware Survey.

[kisak-valve]

I expect that 11GB with the iGPU is the maximum allowed reported by its Vulkan driver versus the carve out ram reported by the GPU Steam is running on.

I expect that 11GB with the iGPU is the maximum allowed reported by its Vulkan driver versus the carve out ram reported by the GPU Steam is running on.

I was wondering that too... but then why wouldn't it have applied the same logic to the dGPU as well? According to the glxinfo* i posted in my 3rd post, it reports VBO free aux. memory - total (which I interpreted akin to "available") to be 14GB (not 11GB) for the iGPU and 15GB for the dGPU... so the dGPU still reports higher.
