Ultra's auto FPS limiter uses the same solution Nvidia's "Max Frame Rate" option uses, which is typically on par with the RTSS limiter in frametime performance and input lag. So if there's no in-game limiter and you don't want to use RTSS to limit the FPS below the Ultra auto-limiter (in cases you need a lower than 138 FPS limit to prevent max GPU usage), switch LLM to "On," and set the Nvidia "Max Frame Rate" option to the desired limit instead.Defox wrote: ↑15 Aug 2020, 10:46There was one more question.
To get lower input latency in "Low Latency Mode = Ultra" - we need to limit in-game FPS below 138 (in the case of a 144 Hz monitor).
But. If there is no in-game limiter. Does it make sense to limit FPS using the nvidia control panel (as we know it increase input lag)? Will this decrease the input lag or, on the contrary, increase it?
Again, with G-SYNC, the only known difference between LLM "On" and "Ultra," is that Ultra sets an auto FPS limit in supported games. Beyond that, they both reduce the pre-rendered frames queue in GPU-bound situations the same way via an MPRF value of "1" (with G-SYNC).
- G-SYNC + V-SYNC + LLM Ultra = MPRF "1" + auto FPS limit
- G-SYNC + V-SYNC + LLM On = MPRF "1"
