FPS.Adj is in bottom of Display panel. (Bad translation dll if it isn't visible?)

Legacy vsync:
+ More compatible.
- High latency (3+ frames).
- Not compatible with fastest possible/JIT modes.
- 100% CPU usage.
- Slow recovery after missed frame.

Low latency vsync:
- Requires more CPU power.
- Requires display driver that has accurate scanline reporting. (For example some drivers report simulated 60Hz even if mode is something else...)
- Dual core CPU or better required.
+ Very low latency, (if "no buffer" buffer setting)
+ Fastest possible/JIT compatible
+ Variable CPU usage
+ Dynamic timing system, can recover from rare missed frames quickly.
