@Just_NiXra@Pol79432674@Preheatwow Most likely a GPU driver/software (AMD Adrenaline) that’s causing RAM usage spike. My PC is using half it’s ram 15-16 GB out of 32 GB just in Windows. Try the Event Log viewer -> Applications -> ID 1001 regarding Kernel activity, clear that log and expand it.
@Pol79432674@Preheatwow If AMD: To disable AMD Adrenalin game tracking and performance overlay, open the software, go to Settings > Preferences, toggle off Game Adjustment Tracking and Notifications. For a full stop, disable the In-Game Overlay and Metrics in the same menu or within the Performance tab.
