Here are the specs:

I have a old Lenovo ThinkCentre M83 that I bought refurbished couple years ago

Core i5-4570 @ 3.2 GHz

8.00 GB Dual-Channel RAM DDR3 @ PC3-12800/1600 MHz (2 of 4 GB M378B5173DB0-CK0 sticks)

GTX 1650 D6 OC Low Profile 4G Graphics Card (GDDR6 edition)

I previously had GT 1030 (GDDR5 one, not GDDR4 version. But it was passive and has no fans and MSi Afterburner said it was reaching like 81 C when playing GTA V, at idle it is 40 C). My neighbor got bored of his GTX 1650 LP and sold it to me for $120, I haven't installed it yet.

I have Xbox Gamepass Ultimate and Xbox One S console but they didn't release Microsoft Flight Simulator (2020) for console yet, I can play it on PC only

Lastly, I was playing GTA V on GT 1030 last night because Epic gave it free earlier this year. It was kinda weird like the texture quality felt it was better than my Xbox One S, and was running at solid 30 FPS (sometimes dropping to like 25 FPS) on my poor GT 1030. Am I just imagining stuff or is GT 1030 better GPU than Xbox One S?

And last question, dunno why if I add too much tracking in MSI Afterburner, it slows my games a lot, so I only track GPU usage% and temp. If I add CPU usage% and temp monitoring/RAM monitoring, etc. GTA V gameplay become so sluggish and choppy.

Thanks
