I tried both ways to limit the fps and both worked fine in my computer
, now it's a matter of taste of wich one is better.
Vsync will bring the most beautiful picture. Stutter and tearing free. So fluid. I use it for every game I play except simracing where ultimate lowest input lag is my primary concern. Either way, make sure to have max pre-rendered frames set to 1.
If you are new to this stuff then...
Study
Watch the following video and learn from it. Keep it handy to refer back to:
Drive
1. Enable TC (traction control) and ABS (antilock brakes) on high/full and SC (stability control) on low.
2. Drive for a few hours, a day, a few days - whatever - until you get consistent and comfortable and a general feeling of control and confidence with the car. A constant comfortable feeling though, not just the odd comfortable lap here and there.
3. Disable SC but don't touch ABS and TC yet.
4. Repeat step #2
5. Lower either TC or ABS (not both) by 1 level (e.g. high/full to medium).
6. Keep repeating step #2 followed by step #5. Eventually you'll have all aids off.
NOTE: If using the Aussie V8s then make sure to also enable, and keep enabled, autoclutch so as to have the car autolift and autoblip for you. If you want to be responsible for upshifting throttle lifts and downshifting throttle blips then disable autoclutch but for now I highly advise to keep it enabled.
P.S. Feel free to add me on Steam. I'd be more than glad to go online and help you out (or just do some racing if not necessarily looking for help). That goes to anyone and everyone
