I confirm:

• N/a that I haven't found an existing compatibility report for this game.
• that I have checked whether there are updates for my system available.

Symptoms

Reproduction

• The last few days I have played these two titles in DX12 interchangeably, back to back

• I am not sure if it is necessary to play the games back to back to reproduce the bug, or it simply occurs on all dx12 titles at random times after a period of gameplay

• Launch and play ready or not, selecting dx12 from the popup when prompted at launch time

• After a couple missions I get the exact same out of memory popup pictured above

• Launch and play insurgency sandstorm with -dx12 in the launch parameters, after a random amount of time (0-3 games?) the above popup is shown

• If I play the games in dx11 (sandstorm without -dx12, and clicking dx11 in the popup for ready or not), they run fine (although at lower frame rate)

I'll try find some more dx12 games to find if the pattern extends to all of them, or if it's just something odd about these two. I assume there's something different about my system because I've run into a few others with the 6900XT that don't have this problem playing dx12 games.

Start with the attached steam-581320.zip compatibility report and the linked system information Gist, then compare the DX12 and DX11 launch paths described for Insurgency Sandstorm and Ready or Not. Reproduce the out-of-memory dialog after several missions and determine whether it is specific to these games or occurs across other DX12 titles; done means a reliable scope and actionable evidence.
