My mouse lags and my DPI drops when using 1000hz

[FrogSlayer66]

Hey so I've got a problem with my current mouse (Logitech G403) but it existed long before it on other mice. No matter which one I use (had Razer Chroma and Zowie FK2) my mouse has weird lags or stutters when I try to move my camera in Rainbow Six Siege, I feel like my DPI drops insanely low even though it shouldn't interfere with it. I'm not sure if it's a USB port problem, mouse problem or maybe my computer isn't good enough. I tried multiple other USB ports, changed my computers case and my GPU. I'm sorry if my english isn't that good, if you have a problem with understanding something just tell me and I'll try to explain it better. Here are my PC Specs:

Processor Model: i5-4460 (3.2 GHz, 3.4 GHz Turbo, 6 MB Cache, 84W)
RAM: 8 GB DDR3-1600 (PC3-12800)
Motherboard Chipset: Intel H97
Old GPU: GeForce GTX 760
Current GPU: GeForce GTX 1060

Have you tried using your mouse on another device? Might be a crucial way to ascertain if it's a PC issue or the mouse.

Unfortunately I haven't because I don't have any other device or pc to check it
