The impact of Antialiasing (AA) mode on Crysis 3 MP Beta’s performance with Geforce GTX670

I had a little spare time today and managed to measure how antialiasing affects Crysis 3 Multi Player Beta’s performance on my GTX670.

Please note that this is not very accurate because the game play is not identical between each. That’s impossible right now. Hopefully there will be a benchmarking mode in the full game. Then it would be easier to compare the performance with others.

Test Configuration

  • CPU: Intel Core i7 2600k @ 4.5GHz
  • RAM: 16GB DDR3 9/9/9/24/1T
  • Motherboard: ASRock Z68 Extreme4
  • Video Card: Palit Jetstream GTX670 @ 1176MHz (313.96 beta drivers)
  • Audio Card: Creative X-Fi Titanium
  • Disk Drive: Samsung 840 250GB (rest is not important)

Frame rate was measured by FRAPS for more than 2500 frames. Some even more than 5000 frames, but as the performance got worse with stronger AA, I didn’t want to play long enough.

There isn’t really a point in comparing the min and max frame rates because it is not the same gameplay. But you should be comparing the average frame rate.

Obviously, running with no AA is the fastest, but it seems SMAA 2TX gives you the best experience overall. I hope the performance would only go up from here. The game will be hopefully optimized a bit and the drivers improved a bit. If we can hit 60fps on average with SMAA 2TX, then it would be a awesome.

Frame times

For interested parties, here are the frame time charts. AA doesn’t necessarily introduce any big lags. The lags are there, but it’s not bad. Let’s hope the up coming drivers will lower the rate of lag further.
