Hi, in the end of 2016 I bought this laptop. It's a used laptop, but it was like 2 years old when I bought it. But the problem is... it's very slow. GTA 5 used to play at ~50fps avg on 1366x768 medium, but now it gets ~30fps avg on 800x600 medium. Also Rocket League, used to play it at 60fps+ with max settings, but the lowest settings now won't get any near that. I've tried a fresh install of every Windows version that's still usable in 2018 (7, 8.1 & 10), but no difference. All drivers are up-to-date. Also cleaned the inside of the laptop & replaced the thermal paste. Temps are ~40-50 idle so that should be fine. Here are some of the specs:
I5-2430m @2.40GHz 2c 4t
8gb ddr3 mem
GeForce GT520MX + Intel HD Graphics 3000 (tried both gpu's btw, gt520mx is faster as excpected, still lags as I said)
750gb 5400rpm hdd (I think it's some kind of Western Digital)
Intel Centrino Wireless N100 - Update 31/10/18: I upgraded the network adapter to a 5GHz one, the TP-Link Archer T1U AC450
Asus K53SC-SX404V
Intel HM65 chipset
