I've got an i5 12400F, an RTX 3060 Ti, and 32GB of DDR4 RAM running at 3200MHz. Two years ago, I was easily playing Fortnite on medium-high graphics with 120-144fps. Now, I find myself struggling to hit those frames, needing to set everything to low just to reach similar numbers. I've added more fans and replaced the thermal paste, and temperatures are actually lower now, but I still see no improvement in fps. Back then, I could run the game at 60fps with ray tracing on without issues, but now I'm getting only 30-35fps and the game often takes longer to load. What's going on?

How do other games run on your PC? If everything else works well, then it might just be Fortnite itself. With all the updates they push, your hardware may not cope as well as it used to.
Have you changed anything with your internet? Sometimes it’s not just the PC itself that impacts performance. Things like a new microwave or moving the modem can influence your network speed. More devices on the same network can also slow things down.
Another thing to consider is whether your monitor is plugged into your graphics card instead of the motherboard, but since the 12400F doesn’t have integrated graphics, that's probably not the issue. If you're still having problems, a fresh Windows installation might help clear things up.
First thing I'd suggest is to check your graphics drivers. Sometimes, just an update or a reinstall can solve a lot of issues. With games like Fortnite that get frequent updates, it’s easy for drivers to get out of sync or even corrupted. Also, take a peek in your task manager to ensure your RAM is still running at 3200MHz. If your BIOS was reset or you had a boot loop, it might default to lower speeds, which would really hurt performance.
