In most games, lowering the graphics settings or resolution barely changes my frame rate. Sometimes I gain only around 5–10 FPS, but often there is no improvement at all. My system has an Intel i3-10100F, GTX 1660 Super, and 8GB of RAM. What could be limiting performance, and what should I check before upgrading?

The i3-10100F is still usable with a GTX 1660 Super, but newer CPU-heavy games may struggle with its four cores and eight threads. Upgrading to 16GB of RAM is a sensible first step because 8GB is now a common cause of hitching and background-memory pressure. After that, consider a faster compatible processor if your motherboard supports one, or move to a newer platform if the upgrade cost is too high.
The first thing I’d do is monitor GPU utilization, per-core CPU usage, RAM usage, temperatures, and FPS during a demanding section of a game. If the GPU is near full usage, lowering resolution should normally help, so a small improvement could indicate another limit such as a frame cap, V-Sync, thermal throttling, or a game-specific bottleneck. If the GPU is underused, the CPU, memory, or another system component is holding it back.
Make sure the game is not limited by a frame-rate cap or synchronization setting. V-Sync, an in-game FPS limit, or a driver-level limit can make lower settings appear to do nothing because the game is already being held at a target frame rate. Also check that the monitor is connected to the graphics card and that the GPU is running at its expected clock speed.
This usually points to a CPU bottleneck. Lowering graphical settings reduces the workload on the GPU, but it will not help much if the processor is already limiting how quickly frames can be prepared. Check your GPU usage while playing: if it stays well below 95–100% while one or more CPU cores are heavily loaded, the CPU is probably the restriction. Your 8GB of RAM can also contribute to stuttering and poor performance, especially in newer games, because the system may have to rely on the storage drive when memory runs short.

CPU usage can sometimes look low overall because games do not use every core evenly. It is worth checking individual core usage, GPU usage, temperatures, and clock speeds rather than relying on one overall percentage.
