I have a bit of a weird one.
Sometime ago my old Nvidia GTX560 Ti died. I don't have the ability to replace the card at the moment so I've been using my onboard Intel HD 4600. I must say I'm pretty impressed by what that little GPU on die can do.
Anyway, I'm having some really weird issues.
Currently I'm on driver 10.18.10.3621 Let's call it the New driver. What happens basically is that many games (specifically OpenGL and possibly?? older DX games) have rather severe graphics corruption. Basically textures flicker wildly, sometimes polygons draw at wild angles. It makes me think of some sort of memory corruption.
Also, the FPS can vary wildy, games stutter, etc. Newer games (Dx9+) do not seem to have this issue.
Here is a demo video. Note that it is *far* worse IRL, the recording software is only picking up a small amount of the issues. Games are almost unplayable.
Here is the intel information center details.
I tried to downgrade to the previous version to see if it would help. Version 188.8.131.5296. Let's call it the Old driver. Surprisingly enough, all of those issues disappeared. Games ran perfectly smooth with no artifacting. However sometimes on occasion the graphics driver itself hard crashes. The screen flickers of rainbow colors very rapidly... I've never seen anything even remotely like it. It seems like through google that this "Rainbow screen of death" is an issue of a rather fatal Intel GPU crash. That would seem likely since it has only ever appeared on THIS driver version with THIS GPU.Intel(R) HD Graphics 4600

So, recap. The new driver is completely stable, but many games, specifically and OpenGL PERHAPS DirectX games suffer from really strange artifacting of sorts.
The old driver is completely fine and stable, but crashes the system.
So I'm forced to use the new driver and really limit what I can play. I'm not sure what direction to go next. I realise I have no left much info but I'm unsure as to what information is required. I do not believe there is any hardware issue otherwise I'd of seen other indications. It is certainly not a heat issue as I have rather effective cooling and I'm in the middle of a rather cold winter. Besides I've monitored the temps.
I'm pretty much stuck on how to improve things right now.
