Identify the limiting factor Detecting the constraint
Hey everyone, I'm testing Fortnite in performance mode. My 3070 ran smoothly at around 240fps, but it dropped to about 190 during endgame scenes. I switched to a 4070 Ti Super and it matched the performance. My current setup is: an i7-13700K, 4070 Ti Super with NVMe SSD, 1TB SSD, 870Evo 1TB, Corsair 850W Mobo, MSI Z690 Edge Wi-Fi, DDR4 RAM, and an XPG D50 3200x4 with 8GB per stick totaling 32GB (running XMP). This is the RAM speed limit from MSI. Overclocking settings: 1DPC up to 5333+ MHz, 2R up to 4800+ MHz, 2DPC up to 4400+ MHz, 2DPC 2R up to 4000+ MHz. It supports dual-channel mode. Any tips or info would be great!
Did you perform a fresh Windows setup or rely on DDU to install drivers? You're using a DDR4 board with an 13700k processor, which will set some performance limits but shouldn't be a major constraint. Fortnite's FPS can vary widely, often ranging from 250 to 400 or even lower in certain moments. What are your in-game settings?
Safe mode ddu driver cleanup, fresh drivers installed. Monitor runs at 240hz. I’ve watched some videos where people shoot at 500fps with drops around 350, which is surprising since I’m having trouble exceeding 240. In performance mode, I’m capped at 240fps with low meshes, medium view distance, and everything stays on low. I’ve even tried locking it at 360fps for testing, but it’s very unstable and keeps bouncing unpredictably.
Your 13700K seems to be the main issue here. The 5800X3D at low settings in 1080 performance mode isn’t delivering consistent improvements, especially around 350-500fps. Even though you can reach 240, it’s not enough for a noticeable boost in Fortnite. It feels like you’re spending more than getting back value, especially when compared to the 3070 model. You’re wondering why others can hit 360fps while you can’t.
Track your GPU performance. Consider turning off the Multiplane Overlay MPO. Ensure you're using the newest motherboard BIOS. Which component is handling your CPU heat? How are your temperatures performing?
I need to see when I’m back from work before I checked my 3070 last month. The CPU was around 72°C after a few hours of gaming. It uses an MSI Mag Core liquid 360 V2 AIO. I’m running the current BIOS and checking the multiplane overlay MPO—still no idea what that means. I’ll update once I’m home and run some stress tests. Thanks!
GPU consumption sits between 23 and 26%, CPU activity ranges from 30 to 35%. Peak CPU temperatures reached 77°C, while GPU peaked at 58°C.
GPU performance stays high, but it enters a lower power mode leading to stutters. Keep your GPU above 90% during gameplay. Set a framerate that challenges the GPU. CPU activity appears minimal since most titles don’t demand many cores, and your processor has ample capacity. The task manager displays overall usage, not per-core stats. Consider tools like AMD OCAT, MSI Afterburner, or Intel PresentMon for deeper insights. No details on your CPU cooler were provided.
It uses the MSI Mag Core 360 V2 AIO, thanks for the support! I’ll check the CPU usage again tomorrow evening. Appreciate your help so far!
