I have been playing Star Wars Knights of the Old Republic 1 & 2 on my laptop for about a year with no problems at all, until recently, I did a Windows update and it caused both my KOTORs to have pixelated flickering textures and if I put my camera at a certain angle, the textures go back to normal until I move my camera, I have been pulling my hair out the last few days trying to find out what this new bug is and how to fix it but to no avail, I tried updating drivers, disabling the game graphic options, running the games in capability mode but, again, to no avail, I decided to look at my update history and to my surprise, it updated my graphics card, an Intel HD 4000 graphics card, and the date in which I downloaded the update matches up with when the textures started to bug out, and I am positive this update has affected my games, the details of the update I believe that is causing the issue is:
Intel Corporation - Graphics Adapter WDDM1.1, Graphics Adapter WDDM1.2, Graphics Adapter WDDM1.3 - Intel(R) HD Graphics 4000
Installation date: 18/07/2014 14:56
Installation status: Succeeded
Update type: Optional
Intel Corporation Graphics Adapter WDDM1.1, Graphics Adapter WDDM1.2, Graphics Adapter WDDM1.3 software update released in May, 2014
My OS is Windows 8.1 and both my games are the UK disk versions and have been updated with all the latest patches, I have seen other people having the same problem as me.
