Slow fps on linux #10

Closed sergiobenrocha2 closed 8 years ago

sergiobenrocha2 commented 9 years ago

I'm experiencing some slowdow, ~43 fps in balanced and 56 fps in performance. This, in a core i7 4700HQ, xubuntu 14.04.

Some time ago, they had high cpu usage, much more than mercury.

perf of balanced core:

bsnes_balanced_perf_top

perf of performance core:

bsnes_performance_perf_top

the cores haven't really changed though, this might be more of a setup issue than a bug

sergiobenrocha2 commented 9 years ago

setup? Well, I'm with the default config, I erased the config folder.

I tried with the balanced core from builtbot, it has the same perf. But with Zelda Link to the Past, it has a different perf, running with 48 fps:

bsnes_balanced_perf_top_core_uploader_zelda_link_to_the_past

Ok, now it's 60 fps, but with high CPU usage, nearly 96°C, 141% cpu

sergiobenrocha2 commented 9 years ago

ugh, it's unstable, sometimes it get 60 fps with high cpu usage, and in the same game it drops the fps

Seems @33c43dc fix it
