"Choppy" framerates

Hi people.

So i've recently built myself a new PC:

Sapphire 6800 XT
MSI Tomahawk Max X570
AMD Ryzen 5800X
2x8 Gb Corsair Vengeance LPX 4000 C16 Ram (running at 3600 14-15 -15-36 1800fclk) (I have a further 2 x 8 sticks arriving today in case it's a memory issue)
NZXT Kraken X73
Phanteks 500A case
LG 27GL850-B

All my temperatures are great, cpu stays nice and cool under load, GPU the same (my room is quite chilly all the time so this helps).

When I'm running Warzone in particular, with all the setting on either low, medium or ultra (1440p monitor) my fps is at worst 140ish and sometimes up in the low 200s. But it seems kind of choppy (for want of a better word) gameplay even though I have such high fps but if I enable vsync, it goes absolutely buttery smooth at a locked 144fps. I've tried manually setting the fps to 144 in the game menu but it still seems nowhere near as smooth as with vsync enabled.

The cpu usage is normally around 30% and gpu about 90% so I don't think they are struggling. Am I missing something really obvious?
 
Warzone does like too use a lot of memory my fps went up quite a bit going from 16 to 32 gig memory

but also check its using the correct amount of cores goto

where every you installed Documents\Call of Duty Modern Warfare\players

adv_options edit this and see what it says for

RendererWorkerCount = 8

it should be 8 for your cpu

if this is wrong can cause lower fps and choppy game play

Does your monitor support Freesync?

It says so on the product page and the option for Freesync is enabled in the Radeon software.

Are you running more than one monitor?

Just the one monitor.

This was set to 7. Just changed it, so i'll give it a go now and report back. Also, just installed the extra ram and there is no difference.
 
Check your refresh rate using the monitor OSD to make sure Freesync is working properly, if the refresh rate dynamically drops when your framerate drops below the normal refresh rate then it's enabled.

Also double check in the radeon settings, make sure you've disabled power saving stuff like Radeon Chill etc.
 
What is the monitor you using? The fact you telling us it's very smooth with vsync 144hz means Freesync is taking over doing its job.

If you getting above monitors refresh rate you be getting tearing making the game feel more choppy.
 
"If the frame rate your computer is producing is different (either higher or lower) that the refresh rate of your monitor, you may experience a glitch known as screen tearing, where information from two or more frames is shown in a single screen draw. It is important to note that screen tearing does no damage to a display or graphics card. To prevent screen tearing, you can enable a feature called Vertical Synchronization, or VSync. This tells your GPU to synchronize its actions with the display, which forces it to render and send a new frame when the monitor is ready to redraw the screen. This does limit your framerate exactly to the refresh rate. For example, if your refresh rate is 60Hz, VSync will cap your framerate to 60 FPS. If your GPU is capable of producing higher frame rates than the VSync cap you can take advantage of its leftover capacity to increase the resolution, draw distance, or other graphics quality settings."

This is why it seems smoother with vsync, the gpu is producing frames before the monitor is ready for them without vsync. Vsync is doing what it is supposed to do, its keeping the gpu in a ready state to create a scene when the monitor wants it. If you want to reduce energy use and increase responsiveness use radeon chill with settings that you are happy with. (some games like warzone benefit more from vsync, freesync and radeon chill)
