I have been trying to resolve an issue with stuttering audio. I only seem to see it on games with chd support, specifically Carnevil, Golden Tee, and some others. (I can't say for certain it is related to CHD, given these games are also relatively heavy in 3D rendering compared to most MAME games) I have tried it on 3 systems, and see the problem on 2 of the 3 of them.
1.) MAME Cabinet (Stuttering): older core2 duo running Win7 , 4GB RAM, budget PCIe GPU
2.) Laptop (Stuttering): i7 (7500U), Win10, 8GB RAM, running on an SSD, and decent mobile NVIDIA GPU,
3. Older Desktop( (no stuttering!) : older i7 (2600K), Win10, 8GB RAM, running on SSD, and an aging GPU.
If the problem was not seen on the laptop, I would chalk it up to old hardware in the MAME cabinet, but if I can get it running well on the laptop, I'll just scrap the core2 duo and put the laptop in the cabinet.
Any advice on where to look or other things to try would be appreciated.
Thanks! -John
