Choppy montage playback

When I play a video I'm editing, it's choppy, it's lag. My computer might not be powerful enough. Here are my specs. Thank you for telling me if they're sufficient.


Processeur	Intel(R) Core(TM) i5-7300U CPU @ 2.60GHz   2.70 GHz
Mémoire RAM installée	16,0 Go (15,9 Go utilisable)
Type du système	Système d’exploitation 64 bits, processeur x64

I'm running Shotcut version 26.2.26.

Thank you in advance
