Very bad benchmark results?

Solution
The results of Userbenchmark already indicate a couple of things of note: incomplete and a lot of background processes running.

However, the score of something like Userbenchmark is no replacement from the monitoring your hardware while you are playing a game (which is what you indicate to be the issue). Use something like MSI Afterburner to monitor your hardware's behaviour. Personally I'd monitor CPU, GPU and RAM usage and frequencies; CPU and GPU temperatures; fps and frametimes; and if necessary page file. These things will give you a better idea of why the game isn't performing well rather than a synthetic benchmark which informs you how well your PC performed in that test.
