Doom Running on low FPS?

Solution
Open 'Task Manager' and while the game is running, check to see if anything else is consuming a lot of CPU/GPU/MEM/HD(if so, disable/end task that app). Make sure V-SYNC is turned off. Make sure all drivers are up to date. Use a hardware monitor such as this: https://www.cpuid.com/softwares/hwmonitor.html (or similar) and check to see if the GPU or CPU are running too hot. If so, you may have to invest in some better cooling.
