Game runs just fine for me.. With a 4790K and 2 1070s in SLI I'm getting 100FPS @ Ultra (that trick to enable SLI by setting force alternate frame rendering 2 actually works). And I'm gaming at 3440x1440. Just saying.. cause SLI in combo with this resolution should really tax the CPU. Maybe an AMD K5 is so old it doesn't have the necessary instruction set?
Edit: it seems most problems occur on laptops, those will severely throttle your CPU due to thermal limitations. AFAIK only Apple has managed to solve this in their latest Macbooks 2016 so the CPU always runs unthrottled. Maybe check the speed the CPU is actually running at when the frame dips occur?
