So recently I purchased a EVGA Geforce GTX 760 to replace my radeon 7770 so I could play so current gen. games on ultra or high. After Installing, some of the current gen. games ran great (such as Battlefield 4, Far Cry 3, ect.) on the new card, but upon checking on some of the old games I played ( like Surgeon Simulator, Chivalry, some parts of Saints Row 3, ect.) it was incredibly laggy and unplayable. Someone recommended that I erased some of the video drivers AMD installed into my computer and that somewhat helped reduce the lag, but it is still there. I cannot tell whether this is a software or hardware problem.
