Most GPU vendors have complex drivers<br />

– Costs CPU, but makes the GPU run faster<br />
That’s ok, reviews compare GPUs using fast CPUs! <br />
Drivers spawn threads that c<strong>on</strong>flict <str<strong>on</strong>g>with</str<strong>on</strong>g> applicati<strong>on</strong><br />
– Driver thread often c<strong>on</strong>sumes an entire core by itself<br />
