All the dlc has its good and bad tbh for me Shanghai is the most demanding.
Shanghai kills the CPU, but if you check Afterburner its not stressing the GPU. I find Guillan Peaks to stress the GPU the most.
Personally ive found siege of shanghai and paracel storm from the base game to be the most demanding. Got premium here and have played all the maps on the expansions.
What about Altai Range? I remember it being really stuttery for me on Ultra on my first few games there but not really played on that map much lately.
Metro when you have 64 noobs spamming rockets, 320's and nades![]()
try Crysis 3 if you want to stress your gpu
