Re: Please help with purchasing a new PC to run sims 4 between $1200 and $2000 AUD
@emz_20_02 That does seem odd, unless you have a giant pile of mods and custom content on this machine that you don't on the other one. (In that case, the logical next step would be to test without your Mods folder.) It's at least worth checking CPU and GPU temperatures to make sure the hardware isn't throttling. There are plenty of free apps out there if you want to look around; the one I prefer is hwinfo. It picks up almost every sensor it can find, which can make the info a bit overwhelming, but you can focus on only the temperature readings to keep things simple.
For reference, your graphics card shouldn't go above 60-65º C when running Sims 4, depending on the cooler it has and the room's ambient temperature, but anything below 80º on the chip itself is fine. (The hotspot will be hotter, naturally, which is also fine unless it's approaching 100º.) The processor's temperatures can be more variable depending on the cooler you're using and how you've arranged the case fans, but it should still never go beyond the low 90s. If it's higher, it's probably throttling to protect itself and thereby tanking performance.
