I would also like to add, if I may, that RTSS stopped doing what it was supposed to on my Radeon Pro 560X with each of the last two Windows system and graphics card driver updates. That was unsettling for a moment because usually the program is rock solid, but in both instances I found that updating RTSS as well to its most recent version fixed everything again. And yes, making sure that it is actually running and that I haven't accidentally quit RTSS in between game sessions.
TS3 has no functional built-in fps limiter because the game was designed in 2008-09 and at that time most (not all) home consumer graphics cards were not capable of even being able to throw such high frame rates. There were some outliers back then like the super powerful GTX 280s and AMD's HD 7900 series, but most players who had cards that were so high-end back then one would hope know how and what to use to tame their cards so as not to burn them out. That's just not true anymore, mid to higher end GPUs are much more mainstream now, but EA would likely have to dismantle the entire program to add or make this feature work properly and the game has been out of development for far too long for them to do this. It can't possibly be a five minute job or they would have done this already, long ago.
In theory, we shouldn't need the third party tools. Nvidia's control panel should be able to cap the fps explicitly and the newest versions of that panel now do this. Radeon's built-in tools should also do this by way of vertical sync, but it just doesn't work for many to most of us and still needs some help.
