VM1: VirtualBox 8, Patcher9x v0.8.50-beta4, Windows 98 RTM, SoftGPU v0.4.2023.19-alpha, AC97 sound card
VM2: VMware 17, Patcher9x v0.8.50-beta4, Windows 98 SE
Host: AMD 2400G CPU, Windows 10
Sound stutters after apply Patcher9x. Deactivate "nested paging acceleration" in VirtualBox VM settings, problem temporary solved. Unfortunately it cannot deactivate nested paging in VMware 17.
Patcher9x works fine in host with Alder Lake CPU.
