Someone (maybe Joe, maybe me) had started coding a -benchmark command line option and not finished. I just checked in changes that finish the code. Now if you run
the game will run, load the replay ~/.vdrift/replays/benchmark.vdr, and then play it. When it's done the game quits and prints out the total playing time and average framerate on the console.
No controls work during the replay playback except for ESC, which immediately quits the replay. Soon I'll set it up so you can specify which replay to benchmark with instead of hard-coding the filename.
Please test and tell me what you think...
