So the underlying issue here is that the two cards returned by vkEnumeratePhysicalDevices are effectively identical, so we try and select the same card we had before, and since they both match it picks the first. We also end up defaulting to the first because we have to mostly assume the first one is the primary, given no other viable information on that matter. It'd be beneficial, if the performance difference isn't resolvable, to somehow return the "primary" card first in the vkEnumeratePhysicalDevices list. However, we'll track the failure to remember internally and see if we can deal with it for now based on the order we're given the duplicates.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
