I have a Ryzen 5 2600 and a GTX 1050ti. I mainly play fortnite which I limited to 144fps. My CPU is always 30 percent busy and my Graka 80. But again I still sometimes less than 144fps although the graphics card has only 80% utilization
The displayed load refers only to the processor in the card, the limiting factor can be, for example, the speed of the memory of the card, you just can't see that.
YES!
The 1050ti is an absolute minimum (worse is hardly possible).
Absolute beginner card.
Only underbody of GT 1030 and RX 550/560.
Not from 1030
The GTX 1050Ti is located in the beginner area. Depending on the game, she is already reaching her limits. In the processor, you can easily block a model from the upper middle class.
Of course, the GT 1030 is even worse than the GTX 1050.
