    Bug Report: Vega M GL and i7-8705G Graphics Switching lag spike

    3ddoman

      Hello, I recently purchased a Dell XPS 9575 2-in-1 with i7-8705G and Vega M GL GPU and it's been great so far except for a bad gaming bug.  In NBA 2K17, the game runs smoothly for a few minutes until a massive lag spike occurs for 5-10 seconds before normal gameplay resumes.  With Task Manager open while gaming, I can see that GPU usage suddenly drops to 2-9% at the onset of these lag spikes while Intel HD Graphics 630 usage simultaneously hits 99-100%.  This isn't triggered by anything specific in the game, as it can even happen while the game is paused.  It seems like the GPU is just randomly turning off, causing the CPU to be overburdened, likely due to a driver issue.

       

      I've uninstalled and reinstalled the application in question as well as both the Intel and AMD drivers, but the issue still persists.  Sometimes, the game will run smoothly and this won't happen, and I have no clue why that is!  I've tried messing around with a bunch of different settings in the Radeon Settings, but none of these settings seem to impact this bug specifically.  Has anyone here had any experience with this, or with similar issues?  Are there any solutions, such as a  specific driver version combination that works best for gaming currently on these chips?  Is it possibly due to some setting that I'm just unaware of?  Again, I'm rather pleased with this device and this CPU/GPU combo, but this bug is very troublesome.
