free sync only working on ship

[Sainray]

Free sync isn't working in game. only working in menu and on the destroyers since last patch.

AMD Freesync is AMD's VRR, or Variable Refresh Rate Technology, for monitors that support said technology.

In some cases you must activate this feature on both the monitor itself, in the monitor's OSD ( On Screen Display ) Menu, and enable it in the AMD driver under the display settings in the driver.

This technology works within a set range of Frames per second(FPS).

Example.

Some monitors can only do VRR at 48-75 fps. If your frame rate in game exceed the range in anyway, by going beyond the upper or lower bounds, VRR will temporarily be disabled until you re-enter the VRR window again.

This was just an example of an older budget monitor a buddy of mine had at one point.

I am using one with a range of 48-240 Hz.
I have an older monitor that has a range of 30-144 Hz on display port and 30-120 on HDMI.

The monitor, the choice of display cable, and the VRR range the monitor supports are all very important for you to know so you can set a proper limiter in place to stay inside the VRR range and keep the feature engaged.

Now you must also stay above the lower limit. If your game's graphics settings are to high and the game is to demanding for your hardware, you will not be able to keep your FPS high enough to stay within the VRR's lower bounds and will exit VRR until you are back in the VRR window the monitor can support.

Some monitors have LFC or Low Frame Rate Compensation, this technology will help maintain VRR even if you fall out of the lower bounds window but only temporarily and only for a short time. You do need to maintain a certain level of performance and stay inside the VRR window to really maintain it's use. LFC really only helps for a few seconds if the game for whatever reason dropped below the VRR window for a quick loading screen or a quick explosion that overwhelmed the GPU/CPU and caused a minor performance dip. It cannot help you if your Fps is regularly falling below the minimum fps line the monitor's VRR window is designed for.

Nvidia's Gsync works exactly the same way. This is why a lot of people ask for frame limiters in their games now a days or they use a frame limiter in their driver set or using some 3rd party application like Riva Tuner Statistics Server.

So to really help you, it would help to know what monitor you are using, so we can determine your monitor's VRR range, and also what your in game performance is like, are you maintaining the minimum level of performance required to stay above the monitor's VRR minimum to maintain VRR.

I highly recommend installing something like MSI afterburner, which will install RTSS(Riva Tuner Statistics Server) along with it as it is needed to run MSI Afterburner properly. MSI Afterburner will allow you to monitor in game FPS, among a host of other metrics, and Riva Tuner Statistics Server, which is required to run MSI Afterburner properly, will allow you to set a frame limit that I feel is superior to the AMD driver limiter or most in game limiters due to how it handles frame deliver and frame pacing of those frames vs the other solutions.

MSI Afterburner Monitoring Tool:
Download the beta version, 4.6.6, especially if you are using a modern graphics card.

Riva Tuner Statistics Server from Guru3d:
Download 7.3.6 Final as MSI will install with 7.3.5 but you really do want 7.3.6 if you are using anything fairly modern.

Hopefully all that helps you and anyone else who might have a similar issue and comes across this post. Cheers. Let me know if you have any questions.

This is just a guess, but you may have to swap between borderless window and fullscreen a couple of times to get it working again. Helldivers 2 is very lax when it comes to enforcing full screen, and full screen can change to borderless window while still displaying that its in full screen. Ive even had instances where its actually in a window with a titlebar and border, and the game thinks its in full screen when i check the menu.

Its my understanding that sometimes Freesync can have issues when not running in true fullscreen modes, however i only have 2nd hand knowledge of this and no personal experience. Worth a shot to try just swapping from fullscreen to something else, and then back again on planet (regardless of what the option says when you look at it) and see if that fixes it.

For me, borderless window says its running at 60fps (vsync) in MSI afterburner on the ship, with no frame stuttering, however when i move the mouse its very clearly not running 60fps. Putting it into full screen solves that issue for me, and while not related to Freesync, theres definitely some weirdness going on with borderless window rendering.
