Tech Report Explains Its Unusual RX 470 Frame Time Results

[HardOCP News]

The crew over at the Tech Report encountered some unusual frame time results while reviewing the AMD Radeon RX 470. Having gotten to the bottom of the issue, they have posted an explanation of what happened and have rerun their tests and posted their findings after fixing the issue.

Pride goeth before a fall, of course, and the DPC latency issue vanished with the new ASRock firmware installed. The frame-time plots for GTA V began to resemble the flat, tight lines we've come to expect with modern hardware. I had to quash the urge to drive over the motherboard a few times and burn the remains before coming to grips with the fact that I would have to throw out large amounts of testing data.

Oh wow thanks for the link! Didn't know DPC latency could cause all that stuttering!

If you read closely, the data for Doom, Crysis 3 and The Witcher 3 did not change, but the feel did.

Everyone makes mistakes; it's how we handle them that counts, and Tech Report gets top marks here.

Right on. Sadly, it is a rare treat to see such honesty in the journalism world.
