The frames continue to decrease under 90 in Fortnite
The frames continue to decrease under 90 in Fortnite
I recently shared a post about my stuttering problem, which no longer occurs. However, I experience frequent frame drops in Fortnite—going from 144 to 80 or lower—and it happens quickly. The GPU usage stays around 40-55%, while the CPU is at 50-70%. I’m unsure why this is happening despite everything being fine a few days ago and temperatures normal. I can increase my settings to boost the GPU to 80-90%, but the issue persists.
I don’t have specific system details. The game may be playing on either an SSD or HDD, but performance can vary based on hardware.
Ryzen 5 5600x rx 6750xt motherboard from ASUS B550F gaming setup. 2x8GB DDR4 RAM at 3600MHz. RIPJOWS RAM with ASUS Thor 850W PSU M.2 wd black 250GB. OS installed on a 1TB WD Blue SSD connected via Corsair H150i.
With those specs, I would think that frame dips that low would be pretty rare and limited to initial loading. Do these dips mainly happen when you start up a new game in the area waiting for the bus and/or during the drop from the bus at the start? If that's the only time you get FPS dips, that's totally normal, as that's when everything is loading into the game for you. On my system with a Ryzen 9 5900X, which isn't a ton faster for gaming than your 5600X, I sometimes get pretty severe frame dips when initially loading into the game and during drops from the bus, but after that, it's pretty rare for it to dip. However, I do have 48GB of RAM, which means that the game doesn't have to swap data on and off from the SSD as often. Do you have anything open on a second or third monitor that could be using up RAM and making the system need to use the page file? EDIT: Looking at this video from Iceberg Tech, it looks like Fortnite can benefit a lot in FPS lows when going from 16GB to 32GB of RAM, even without having things open in the background. Apparently the game is more RAM hungry than I realized.
The high GPU demand suggests the CPU is limiting performance. You might be using reduced graphics settings or enabling v-sync.
I suggest moving to DX11, as it tends to perform more reliably than DX12, especially for stability. This could be a short-term fix to address your low FPS issues. I’d only increase View Distance and Textures to Epic settings while keeping Post Processing and Effects at Low levels. Reducing the others frees up GPU resources, ensuring your card isn’t the bottleneck during intense effects use. Textures set to High or Epic usually don’t hurt FPS if your GPU has sufficient VRAM, and they improve visuals with minimal performance cost.
The configurations applied here match those you demonstrated earlier. I plan to test Dx11 next, though I anticipate it may not perform as well since I encountered performance issues previously.
