CPU bottleneck GPU?

Hi, I recently purchased a Geforce Gigabyte RTX 2060 6GB OC edition to upgrade from my previous GTX 960. In some particular games I have seen good improvements in performance such as Rainbow six Siege, and Escape from Tarkov, however, I feel as if I have some other preexisting computer issues that weren't quite fixed by this fairly expensive upgrade. In most games, I'm getting very little frame-rate difference between low and high/ultra settings such as PUBG, Battlefield 1 and CSGO. In fact, at lowest settings in PUBG my computer seems to perform far worse than when everything is maxed out (same issue in battlefield). I've heard of CPU bottleneck issues and whatnot and just wanted some help to determine whether I should upgrade any other parts of my computer in order to give me a smooth gaming experience, as I feel as if my computer isn't reaching its performance potential.
My computer specs are as follows:
Operating System
Windows 8.1 64-bit
CPU
Intel Core i5 4690 @ 3.50GHz
Haswell 22nm Technology
RAM

Thanks so much,

The three games you named are all very easy on a gpu and murder on CPUs. A 2080ti wouldn't help you on them (well bf is tough on both)

That's odd. I thought the graphics card had 6GB of vRAM.

And I've tried Battlefield V with a 4690K at stock speed and a GTX 1080 ti. I got over 120 fps. It would freeze at times though and it wasn't a perfect experience but it did do better than I expected it to do.

That windows screen rarely ever shows more than 2gb vram
