1 - Check your DeviceConfig.log file (in your TS3 user game folder in Documents, a fresh one is generated every time you startup the game) to make sure the game is using your Nvidia card and not the Radeon integrated. The card may not show as formally recognized, that's a different and much less important issue, but it should still show as a 1050.
2 - On the Nvidia Control Panel, set up a profile for TS3.exe (for Patch 1.69/Origin) or TS3w.exe (with the "w" for Patch 1.67/Steam or all retail disc). The settings should then be Use High Def Card (or something like that), Triple Buffering On, Vertical Sync On (or Adaptive, whichever one works better). Vertical sync only works in full-screen mode.
3 - Have you capped the frame rate of this card and checked the actual frame rates you are getting in-game? The newest versions of the Nvidia Control Panel should also have a Max Frame Rate setting, which should be set to no higher than the refresh rate of your monitor/screen. Most are 60 Hz, so 60 fps but some can run higher. To check the actual frame rates in-game, Ctrl+Shift+C to bring up the cheats console and type fps on (enter). As you play and move the game camera around, the displayed frame rate should never exceed 60 or whatever the refresh rate of your monitor is. To make the display go away, cheats console again and type fps off (enter). Max Frame Rate should work in both full screen and windowed modes. If the Control Panel doesn't lock things in, although it should, we usually move on to adding a third party tool that might do a better job such as Nvidia Inspector.
