Major microstuttering on GTX 1070 with the DirectX8 Sea Dog games

I'm using the 1.7 bugfix-only combined patch for CoAS and though I have a fairly good rig (i5 3.9 GHZ/GTX 1070) I get annoying microstutter every few seconds with these games. I have to use RivaTuner to lock framerates at 60 FPS to get smooth framerates but even when it's smooth, every few seconds I get major microstutter that lasts for a few seconds then returns to normal then back again. I'm using Windows 10 with all recent updates and I tried various compatibility modes. Also using latest Nvidia drivers but tried earlier ones and still the issue persists. Anyone else have this problem and found a fix or is this likely a DirectX8 problem with no fix? I also noticed that when the microstutter occurs my FPS remains constant at 60 FPS so it's not an actual framerate drop just some kind of hiccup.
 
You could try installing/implementing the dgvoodoo 2 package in addition to RivaTuner. It may change/improve graphics performance, seeing as it may override the DirectX 8 emulation in DirectX 10/11 to using proper hardware rendering and APIs instead.

(Bottom line is that Windows 10 is terrible for old-school gaming, though -- and it will only get worse with future updates.)

Okay, I'll try it. Thanks, mate :)
 
Just thought I'd poke my head in here after 4-5 years to say that the DGVoodoo wrapper was definitely a cure-all for the stuttering in CoAS and many many other old DirectX games (ie Indiana Jones 3rd-person adventures) that don't play well on modern hardware. Just be sure to use updated versions of DGVoodoo to prevent window switching bugs with CoAS on modern displays.
