Newer Versions, Older Systems [BUG]

[Michael Vokits]

Thanks for taking the time to write a bug report!

Describe the bug
Alas, no version of NAM after 0.7.2 works on any of my rigs, VST or standalone. I can load things, but doing so makes no difference to the actual sound. Knobs turn, but do nothing – not even in/out volume. No error messages. Also, and this is probably key, the processing is almost absent on 0.7.3 or higher: Tracktion shows me about a good 30% difference in CPU usage between 0.7.2 and 0.7.7, which suggests processing is somehow bypassed?

Desktop: AMD FX-8350, 4.00 GHz, 16 GB RAM, 2014. PresSonus Audiobox USB 96, both input 1 and 2 makes no difference, Tracktion 7, Waveform 11, Bandlab/Cakewalk/whatever they're calling it these days, Live Lite, MiniHost, NanoHost (all x64). Audiobox ASIO, FlexASIO, ASIO4All. Windows 10, 22H2.

Laptop: generic HP POS, AMD Ryzen 5-2500U, 16GB RAM, 2019. Tracktion 7, Waveform 11, ASIO4ALL, FlexASIO, Windows Audio (normal and exclusive), via onboard Reaktek 2496 audio. Windows 10, 22H2.

To Reproduce
Steps to reproduce the behavior:

1. Move the plugin to the VstPlugins directory (ok, I copy NeuralAmpModeler.vst3.new to NeuralAmpModeler.vst3)
2. Renew plugins list
3. Load NAM
4. No error messages, but also no actual changes.

Expected behavior
To affect audio signals.

Screenshots

Desktop (please complete the following information):

• OS: Windows 10, 22H2 on both rigs
• Plugin version: 0.7.3 or newer; earlier work flawlessly
• Standalone on desktop, VST3 on both
• DAW: Tracktion 7, Waveform 11, others also tried
• Audio interface: Presonus AudioBox USB 96 on desktop, std Reaktek on both
• Sample rate: 44.1 and 48 kHz; both work fine in earlier versions (I understand 44.1 isn't supposed to work?)
• Buffer size: 256 samples

Additional context
0.7.2 works great – thank you for an awesome amp sim!
