And for the record;
THAT is why your Ryzen 3 is under-performing. Get another stick of ram for that bad-boy and watch it shine!
That goes at least double if you buy an APU like the 2400G. The chip is using main memory for graphics so memory bandwidth is key. ALWAYS use dual channel and spend the little bit of extra money for DDR4-3200 RAM with an APU. (Note that this means you'll need a B350 or B450 motherboard rather than an A320 because that's technically a memory overclock.) And experiment with the amount of RAM set aside for graphics. Some benchmarks have shown it doesn't matter but I have tried some programs where it DOES matter, a lot.
