Subject: Use gettime(GETTIME_FRAMESTART) instead of gettime(GETTIME_REALTIME) to calculate... 
X-Git-Tag: xonotic-v0.8.5~743^2

Use gettime(GETTIME_FRAMESTART) instead of gettime(GETTIME_REALTIME) to calculate qc fps as the latter becomes inaccurate after a while (at least on Windows 10). It should be noted that gettime(GETTIME_FRAMESTART) returns the value of the engine variable realtime which is used by the engine to calculate the engine fps
