More testing carried out this morning - tried YAME as admin, YAME in Win8 compatibility mode, and reinstalling… all with no effect.
Memory usage at 2D with YAME client running is ~800MB BMS & ~90MB YAME, 55% overall utilisation. As soon as I enter the pit, BMS climbs to around ~1.5GB and YAME spikes as high as 3.3GB, ultimately settling at ~1.5GB. Overall utilisation is pegged at 98%. Returning to 2D returns BMS & YAME to their previous levels (ish) but usage remains pegged at 98% until I kill YAME entirely.
Any ideas at all?
