Hi. Does increase ram improves 4k video lag?(i have 16gb) thanks
Hi Armando, Thank you for your comment on the blog post about playing 4K Ultra HD videos in VLC Player.
To answer your question, increasing the RAM on your computer may help with 4K video lag, but it’s not the only factor that affects video playback performance. Other factors that can contribute to video lag include the graphics card, CPU, and hard drive speed.
Having 16GB of RAM is generally sufficient for most tasks, including playing 4K videos. However, if you’re still experiencing lag, you may want to check if your graphics card is capable of handling 4K video playback, as this can have a significant impact on performance.
You can also try optimizing your computer’s settings for video playback by closing other programs and processes that are running in the background, disabling hardware acceleration in VLC Player, and adjusting the video output settings in VLC Player.
I hope this helps! Let us know if you have any other questions or concerns.
