I now think that it's my GPU throttling itself down due to high temperatures. When running MAME with the HLSL active for a while, I noticed that my GPU temp was approaching 99 degress Celsius! After stopping MAME for a while, or if turning HLSL off, the temperatures quickly dropped to it's idle temp of 60 C. (Yes, this mobile graphics card runs INSANELY hot). So I think that the GPU is throttling, thus causing HLSL to hiccup and MAME to stutter. So I think when I go and look into getting a different laptop some time in the future, I'll ensure I get one with good cooling for the GPU so that it won't throttle on me.
