   Weird aliasing issues
  A few months ago I updated the driver for my graphics card and then started seeing some weird aliasing going on in my game.  After rolling back to the old driver everything looked great.  I thought I had my problem solved and that the driver was bum.  Ends up the old driver might be the bum one.  I recently tried out my game on my wife's laptop and got the same aliased looking crap which now makes me think that this is the expected behaviour with my current setup and I happen to get smooth looking stuff on my machine by a fluke.  Here's the smooth looking one: Here's the aliased looking one: Has anyone had a similar problem to this?  Is this an aliasing issue that I have my D3D device setup incorrectly that my old driver happened to setup correctly?  The only other thing of note that might help is that my textures are fairly large (1024x1024) since I haven't really done a cleanup/perf pass on the art assets yet.I plan on playing around with the device settings this week but was hoping someone might have some wisdom to share which would save me some time.   
  You have probably checked this but it isn't just the anti-aliasing default setting that has changed in the drivers? If you have nvidia you know that you can set AA to on, off or application controlled in display/settings/advanced..?   ;  For completion purposes, and for anyone searching with a similar problem in the future, I have solved my problem.  Ends up my old driver left texture filtering on by default and the new one didn't.  Meaning that I hadn't set up texture filtering correctly.  I just added the lines:m_pd3dDevice->SetTextureStageState(0, D3DTSS_MAGFILTER, D3DTEXF_LINEAR);m_pd3dDevice->SetTextureStageState(0, D3DTSS_MINFILTER, D3DTEXF_LINEAR);to my D3D device creation.Thanks to Sepultang for giving my the idea of switching things on and off on the driver settings tab.  I reverted back to my old driver which worked and started turning things off until I got the crappy look of the new driver.
