NVIDIA NULL and Reflex vs. AMD Anti-Lag and Radeon Boost – which is better? Latencies in practice!

To test AMD’s and NVIDIA’s latency-reducing implementations, respectively, I forced both graphics cards into GPU limit in 1080p. Since both AMD Anti-Lag and NVIDIA Ultra Low Latency can only do their job in this way! I measured again at the same place in the game, so the conditions are the same for both cards. So on your mark, get set and go..

It was interesting that NULL did not work here, suggesting that the back pressure in the render pipeline was not yet fully present. Or that NULL just didn’t work, for whatever reason. In return, NVIDIA Reflex shows us its capabilities, a 48% reduction in latency is quite a feat. AMD Anti-Lag can also show its capabilities, although these are very low. The 4 ms here correspond to only 5 %! An IGFL would most likely achieve a comparable result to NVIDIA Reflex & Boost here.

Furthermore, it answers the question why Anti-Lag is obviously deactivated when Radeon Boost is activated. As soon as you turn on Radeon Boost, Anti-Lag is automatically on. Unfortunately, the end user is confused here in the AMD software, as the switch jumps to “OFF” for Anti-Lag when Radeon Boost is active. From my point of view AMD should adjust this in the software! In the end, however, you can see that Radeon Boost unfortunately doesn’t do anything under static conditions! So if you play the sniper, you can only gain a few ms by anti-lag. Here you have a clear advantage with NVIDIA Reflex.

While the RX 6700 XT was still slightly ahead in the CPU limit, the whole thing turns around in the GPU limit. The average FPS with the RTX 3060 Ti is slightly better and remains at the same level even with NVIDIA Reflex & Boost. The 1% low even increases slightly with NVIDIA Reflex & Boost. AMD clearly loses a few FPS here, as AMD Anti-Lag or Radeon Boost cost their FPS price, as it is an outside intervention on the game via the driver. But the 1% low are better with the RX 6700 XT through the bank, that must be clearly mentioned here for the honor.

I’ll leave you alone with the other slides at this point…

So, here I am again! Since we haven’t seen Radeon Boost in action yet, I’m adjusting the test conditions now and it’s getting more dynamic!
