I'm sorry miljoneir, the PC i had done these runs on recently died so i cant share my config.

However, i used an Intel i5 6600K, a Nvidia GTX 970 and 8gb of RAM.
Additionally, in Wipeout Fusion, you should lower music volume to 0%, and in PCSXE set the audio to mono/flat. Most of fusions lag while emulating stems from audio, the other from the excessive use of alpha effects, can't do anything about that though.

Hope I could help
