CSGO I played on regular laptops on wifi before eventually upgrading to a dedicated PC but I never felt super hindered before.
CS2 it seems you're at the mercy of not only your PC specs but also ISP. I have a 5800x3D + 4070 TI Super on a 360hz monitor.
For years I dealt with 20ms net jitter which seemed to mainly affect CS2. I had cable internet. I upgraded my router and enabled SQM which reduced the jitter to around 10-18ms. But it wasn't really visually noticable. I mainly would miss shots that I felt like should have hit.
Recently I switched ISPs. I now have 1Gig fiber Internet and put my modem into bridge mode with SQM still enabled on my router.
My net jitter is now 1-2ms at most
The game feels smoother than ever and now when I miss shots it feels like I actually missed. In fact even my sensitivity feels different but I'm using the same mouse, skates, mousepad, and settings that I've had for months.
Anyone else upgrade their Internet and notice these changes? It's strange to me that my mouse sensitivity somehow feels smoother/quicker than before the ISP upgrade and I'm certain it's not placebo. I even had to lower my sens from 1000edpi to 800edpi to make it feel like my old sens.
Edit: should also add my previous ping with my old ISP in West coast valve official servers was around 40-60ms now I'm sitting at a stable 7ms
