@LovroMaza The first question is whether you've capped your in-game frame rates. TS3 has no fps limiter of its own, so you need an outside tool. To see your in-game fps, bring up the cheats console (crtl-shift-c) and enter "fps on" without the quotes, and a number will pop up in the upper right corner of your screen. Your fps should never go above the refresh rate of your monitor, which is 60 Hz. (To make the number go away, enter "fps off.")
For Nvidia cards, the first choice is the built-in control panel. But it doesn't always work, and never works in windowed mode, so the next one to try would be Nvidia Inspector (free download). For each, you'd need to use TS3.exe to set up the profile for an Origin install. Here are screenshots of the setups for both tools:

It's also possible that TS3 is using your integrated card rather than the dedicated one, which would explain the low graphics quality. The fps-limiting tools should also force the game to use the Nvidia card, but you can check your deviceconfig to make sure. The card used will be listed about 30 lines down.
Additionally, while the drivers for your Nvidia card aren't particularly old, there should be newer versions available. You can download them directly from Lenovo's website.
I recognize some of the entries in your error reports (at the bottom of the dxdiag), but I don't know what to do with a couple of them. You might need an expert opinion on those; perhaps @roberta591 will have some thoughts.
