I bought a prebuilt gaming PC in September and later upgraded the graphics card to an RTX 5070. It performed well at first, but recently the performance has dropped noticeably. I'm trying to maintain a steady 240 FPS in Fortnite and can't seem to reach or hold it. Could the system have a bottleneck, overheating issue, incorrect settings, or another component that needs upgrading?
The current specifications are:
- Intel Ultra 7 265F
- NVIDIA RTX 5070
- 32 GB DDR5 RAM, possibly 6000 MT/s or 6400 MT/s
- 2 TB PCIe 4.0 SSD
- Liquid AIO cooler
The exact RAM speed and other component details weren't clearly listed by the system manufacturer, so I'm not sure what settings or hardware information I should check first.

Also check storage space and background processes. Keep some free space on the SSD, close unnecessary launchers and overlays, and scan for unwanted software. In Task Manager, look for anything constantly using a large percentage of the CPU, memory, disk, or network. Compare Fortnite’s performance in a clean startup or after disabling overlays to see whether a background program is responsible.
Monitor CPU and GPU temperatures, clock speeds, utilization, and frame times while playing. A prebuilt can have poor airflow or an improperly mounted AIO, causing the CPU to throttle once it gets hot. If the CPU is reaching unusually high temperatures and its clock speed drops, check the pump and radiator operation, clean the filters, and improve case airflow before considering an upgrade.
Start by checking the basics before buying anything. Confirm the RAM speed in the BIOS or Task Manager and make sure the correct memory profile, such as XMP, is enabled. Also update the chipset and graphics drivers, verify that Fortnite is using the RTX 5070, and check whether any power-saving settings were enabled. Incorrect drivers or memory settings can noticeably reduce performance.
I’m not very familiar with BIOS settings. Which screen should I look for to confirm the RAM speed and enable the memory profile?
What should I do first? I can check temperatures and Task Manager while Fortnite is running, then look at the RAM and driver settings.
