UPDATE: Radeon R9 295X2 In CrossFire: 25 Billion Transistors Game At 4K
By

For the first time, we observe significant difference between the FCAT- and Fraps-reported benchmark results using Thief’s in-game test. FCAT tells us that there’s a 62 FPS average, while Fraps spits back 77 FPS. But Fraps also tries convincing us that the game dips as low as 6 FPS and shoots as high as 1174 FPS, which surely throws the average out of whack. The FCAT number is far more believable, dropping to 16 FPS, and peaking under 90 FPS. That’s scaling in the 38% range, which is not great.

What’s up with the big difference between FCAT and Fraps in this title? Using four GPUs, the Thief benchmark exhibits strange behavior in that it starts, chops through a few seconds, and then spits out a rendered payload in faster-than-real-time until it catches up with where the action is supposed to be. AMD suggests to us that this could be due to the app compiling thousands of shaders upfront, affecting performance. If you play through the game for several minutes, the frame rate does even out a bit.

The big drop in performance happens at the end of the test for no clear reason.

Two Radeon R9 295X2s in CrossFire again yield the highest worst-case frame time variance, though I normally don’t consider the 6 ms-range problematic. We do know, however, that results in the 5 ms range can be distinguished in blind testing, depending on the title.

Big frame time variance spikes are indicative of our biggest problem with the Thief benchmark: severe stuttering. As with Battlefield 4 the experience in Thief simply isn’t acceptable. The issue was confirmed when we went into the actual game and encountered the same stuttering issues.

    What does the power meter say about it's power levels? ITS OVER ONE THAUSAAAAAANNNNNNND!

    Good Lord above... that sucker must contribute DIRECTLY to global warming LOL,

    If you can't type numbers as words, don't bother trying.

    At what bit-depth is testing done? Shouldn't color bit-depth be 10 for UHD testing?
