Do i really need to put half of my monitor refresh rate for FG or can I put it lower ?

[Dandenno]

I have 120 hz, i see everywhere that it is recommended to put 60 fps limit in game before using the x2 for a 120hz screen

But what if i only want 80 or 90 fps for example ? Can I put the limit at 40 or 45 without any issue or is there a downgrade from the 60 fps limit to 120 ?

for Horizon Forbidden West
I locked it at 30 fps to target 75, x3 frame gen. quite stable still.

you can have your take on what fps to cap. but the higher native fps should bring better performance.

in fact you cam also change your monitor refresh rate to your target fps

Yes, that would be ideal for the frame pacing.

[kripcision]

no you dont need to set it to any particular frame rate.

If you only want 90 FPS, you can of course cap your game at 45 FPS to get a stable frame time, but if you can reach 60 stable FPS in your game, you will probably get a better result with less input delay and more frames once upscaled to 120.

With the recent update the software can even triple your FPS with the upscaler x3 which means you can cap your frame to 40 FPS in your game and achieve a stable 120 FPS.

no don't cap your frames

you should cap to a framerate, that is stable on your system. if in doubt, use half the refreshrate of the monitor and use LSFG 2x.

If you limit to 40fps and interpolate to 80fps on a monitor that's running at a 120hz fixed refresh rate, your frames will be displayed at uneven time intervals (2x-1x-2x-1x etc.) leading to a juddery presentation that's unlikely to look better than 60fps.

You could see if you can add custom resolutions/refresh rates to your monitor via your GPU's control panel or "Custom Resolution Utility" (CRU for short), and add for example 80hz or 90hz refresh rates.

Alternatively you could see if using LSFG x3 is an option.

But on a fixed refresh rate monitor,you want to interpolate from half refresh rate to full refresh rate and then set graphics settings so you have about 20-25% percent GPU headroom after upscaling/interpolating.

If your display supports Free/Gsync you might be able to interpolate 40 up to 80 smoothly, but i personally have no experience with this.

i use freesync and its fine at whatever fps is in the freesync range (for me its 48 - 100 hz/fps)

Nice. Have your come across games/scenarios yet where the base framerate is too varied and it maybe throws LSFG for a bit of a loop?

thank you all for the answers !!
