Re: 3 windowed icon in the top left

Unfortunately the screenshot is showing a cpu bottleneck. Client Frame Time (CFT) is 31ms which is equal to 32fps. (1,000ms ÷ 31ms = 32fps)

If the PC frame rate goes below the Server Tick Rate (STR) of 45Hz this will cause the Time Nudge (TN) to increase to a massive 623ms. This will cause players to teleport around because now the PC has to interpolate player movement because the PC frame rate is below the server's 45Hz tick rate.

The 3 rectangular squares in the top left corner mean the PC framerate is below 45fps.

Check to see if any other programs in the background are using the CPU. Put Battlefield 2042 and window mode by pressing Alt + Enter. Then bring up task manager alt + ctrl + del and set it to 'always remain on top'. Monitor cpu usage while playing.

If CPU usage is maxed then the CPU is running at it's limit. The only option is to play smaller game modes that are less cpu intensive.

Double check that RAM memory is running in dual channel mode using CPU-Z. Check CPU temperatures with hwinfo. Temps should not be higher than 90°C.

Make sure the E cores of the CPU aren't being used for gaming. If for some reason they are then disable them in bios.
