Re: Apex Legends Stuttering after latest update

@CroL0coNvidia's Ultra Low Latency mode does limit FPS to avoid G-Sync ceiling, which means overlaping with V-Sync frequency. For example, having 144 Hz monitor and G-Sync+V-Sync enabled, the ULL will cap FPS to 138. Higher the refresh rate - more significant the cap is (e.g. 189 FPS on 200 Hz). Not sure though, what happens if you disable G-Sync. I suppose that FPS cap will be disabled too, because there is no risk of constant switching between G-Sync and V-Sync.

And avoid using Nvidia's or in-game FPS limiters. Nvidia's has higher input lag than RTSS and in-game has no constant frame times. Use Riva Tuner Statistics Server (RTSS) fps limiter instead.

    That explains why my FPS is capped to 162 (on a 170hz monitor) even though I set the driver limiter to 165. Thx for the info mate. 

    So if I want to use g-sync and ultra low latency the setting would be:

    1. Turn on g-sync
    2. Turn on ultra low latency mode
    3. Don't touch the FPS limiter in drivers, Riva Tuner or in game command
    4. Turn on v-sync in drivers

    ??

    @CroL0coExactly! I would add "+fps_max unlimited" to the game's arguments. Otherwise game will lock FPS to your refresh rate by default, which is not necessary.

    @7empePL I just rolled back the driver and it is not working sadly ☹️. I tried disabling LLM both in-game launch options and in Nvidia. I also tried enabling it in Nvidia and adding the +fps_max unlimited command but it did not work. I might mention here that the FPS drop is associated with a sound stutter as well. This has been the case in the lobby though, I didn't pay attention in an actual match if that is the case though.

    @7empePL I noticed right now "+fps_max unlimited" or "+fps_max 141" or "nothing" on command launch doesn't matter if I use Ultra Low Latency on Nvidia Control Panel, always 138 fps with stable 7.2ms.
    PS: Impossible to play Apex without Ultra Low Latency mode on "Ultra", in-game massive stutter incoming otherwise.

    @FasperaDo you play on laptop? What's the spec? If sounds stutters as well, this may be related to the power plan or hundreds of other factors...

    @ON1MUSH4Well it does not matter, because lowest cap takes precedence. However, if different caps are too close each other you may notice microstuttering (it depends on a gap between limiters and limiter's implementation quality). Safe margin should be at least 3 FPS to not see the difference. Setting "+fps_max unlimited" unlocks the game's engine to update the scene to 300 per second. Having 138 cap due to enabled ULL assures that these 138 frames will be always the most current = lower input latency too.

    @7empePL Yes I play on a laptop (Lenovo Ideapad 700-15isk), always have been, and never encountered this issue. My specs are:
    i7-6700HQ
    GTX 950m
    16 GB DDR4

    My current power plan is ultimate performance, but I tried switching back and forth between balanced and high performance.

    bro I have a 60hz monitor, I dont think fps_max 57 would be a good thing...

    last night I reinstalled windows and installed the old nvidia driver that u guys says its the best one now.

    In firing range there is almost 0 input lag and 0 stuttering, and my frind has literally the same pc but he can plays the game without any problem.
