I know V2D is the most widely compatible, just pointing it out; Second, the OSD keeps flashing between OpenGL and D3D10, which is pretty weird; Third, the reported FPS seems to be exactly double the actual value, which I verified using ShadowPlay and Dota 2's own statistics. Let me know what other info I can provide to help address the issue.
Well I actually had the OSD disabled yesterday when I was playing but I would bet this has something to do with the major Dota update that released yesterday. I've never had this issue.
But seriously, a couple more videos I just recorded showing the problem. Double/wrong FPS https://youtu.be/nzbhaU9WEPA OGL to D3D10 and back and forth https://youtu.be/RkgHx258p5g
I'll say that as well. Then seriously recommend to read software system requirements section of documentation and pay attention to statements related to lack of support for laptops.
