907e582f55 Remove latency markers 
Some parts of the engine have to be rebuild in order to implement this correctly, therefore, it has been removed for now to avoid potential performance problems.

fps_max_rt and fps_max_gfx have been limited to 295 to avoid a contest with the engine's hard limit causing huge performance hits.

4927654da0 Bugfix: only run NVIDIA Reflex if we ran an actual engine frame 
CEngine::Frame() tends to return out early if we are ahead of frame time, and therefore need to sleep. In this particular engine, CEngine::Frame() returns true if it had actually executed an engine frame, else it returns false.

Therefore, we end up calling 'NvAPI_D3D_Sleep()' multiple times a frame, and thus causing a major loss in performance. Now we check if we have actually ran a frame (incrementing reflex frame if so). If the frame was not incremented, but 'GFX_RunLowLatencyFrame()' was called, it will not call 'NvAPI_D3D_Sleep()'.

Code has been tested and appears to work on my system (never called twice or more per frame). Needs more testing on other systems to make sure its good.

ea6c15df4c Initial implementation of NVIDIA Reflex Low Latency timing 
Propagated latency markers in an attempt to further reduce input latency. Code is pending rigorous testing on several systems, including systems powered by an AMD GPU to make sure we are not impacting performance on systems that does NOT support NVIDIA Reflex.

07dade5d5d Implement high precision frame limiter 
Limits frames at a much higher level of precision than 'fps_max' and 'fps_max_gfx', probably ideal to reduce input latency even more. Also changed the logic of the NVIDIA Reflex frame limiter, to which it would use the desktop's refresh rate if set to '-1'. The new render thread frame limiter has a similar behavior. Using desktop refresh rates on the render thread or NVIDIA Reflex frame limiter requires 'fps_max' to be set to 0 (unlimited), as it would otherwise result in a major performance drop due to a contest if fps_max_(gfx/rt) is set to a similar number as fps_max.
