A short time ago, I installed Fortnite on my PC, expecting a Minecraft clone with limited performance. Initially, everything functioned well and exceeded expectations. Running at 720p with 60fps was smooth, especially with the Low settings and Ultra View Distance. After the latest update, performance dropped significantly, causing frequent FPS drops from 60 to 40, then fluctuating between 20 and 50. To maintain 60fps, I had to lower all settings and play at a low resolution of 360p. Later, I discovered my integrated graphics were using 5GB of RAM while only 3GB was available, indicating a memory bottleneck. I adjusted the BIOS to set Graphics Memory to 2GB instead of Auto, but Windows still reported 3GB dedicated and 2GB shared. I locked it to 64MB, yet RAM usage remained high. I’m planning an upgrade later and wanted to know if there’s any immediate solution to reduce memory demand.
Here are my specifications:
- Disable iGPU if not in use.
- Share a screenshot of the task manager’s Performance tab with Memory selected.
I'm using an iGPU, please note I missed listing my details earlier. I've updated the information now.
Your message got a bit mixed up. The dedicated GPU doesn't directly affect RAM. I'd still appreciate seeing a Task Manager overview. Could you also check how much RAM the OS is using when stressing it to over 3Gb? Another suggestion is adjusting the pagefile size.
I believe I understood the solution, thank you for your support and guidance!
Chrome tends to consume a lot of RAM when opening many tabs or loading large pages. That’s a common problem. Feel free to send over your solution if you’re facing the same issue.
