Insufficient system RAM can lead to slowdowns and stuttering, especially when running multiple applications or playing memory-intensive games. 8GB of RAM is generally considered the minimum for a decent gaming experience, while 16GB is recommended for smoother performance, especially with newer games.
Storage Speed
The type of storage device (HDD or SSD) can also impact loading times and overall system responsiveness. SSDs (Solid State Drives) offer significantly faster read and write speeds compared to HDDs (Hard Disk Drives). Installing games on an SSD can dramatically reduce loading times and improve the overall gaming experience.
Display Resolution
The resolution of the display also affects GPU performance. Higher resolutions require the GPU to render more pixels, which can put a greater strain on its resources. Gaming at 1080p will generally require more VRAM and processing power than gaming at 720p. The GeForce 840M is best suited for gaming at 720p or low 1080p settings.
Driver Updates
Keeping your NVIDIA drivers up to date is crucial for optimal performance and stability. NVIDIA regularly releases driver updates that include performance improvements, bug fixes, and support for new games. You can download the latest drivers from the NVIDIA website or through the GeForce Experience application.
Conclusion: Balancing Memory And Overall System Configuration
The GeForce 840M typically comes with either 2GB or 4GB of VRAM.
