OBS works differently on different laptops

Hey, everyone,

I have 2 laptops:
A. Lenovo W540 (Intel Core i7-4800MQ @ 2.7GHz, 32GB RAM, Intel HD Graphics 4600, NVIDIA Quadro K2100M)
B. Dell Precision 5560 (Intel Core i7-11850H @ 2.5GHz, 32GB RAM, Intel UHD Graphics, NVIDIA RTX A2000)

and OBS is configured the same way on both of them.

When I start recording on B. OBS starts using the NVIDIA graphics card while on A. this is not the case. I wonder why is that so and how to make B.'s OBS stop using the GPU while recording?

How can I tell if OBS uses the NVIDIA graphics card you might ask? It's simple - from NVIDIA's GPU Activity tool:

Ops, I just found out that I have the same profile name on both OBSes but actually, the Video Encoder on B was set to Hardware and Software on A. I changed that and it's all good now.
