Throwing money on issue is not solution. It’s avoiding problem that not everyone can afford to do.
EVE by default has interval settings on. I assume that OP just used one of predefined settings and they don’t change interval options. So fps limit should be on.
Yet, it is better than minimal requirements on CCP website… https://gpu.userbenchmark.com/Compare/Nvidia-GeForce-8600-GT-vs-Intel-HD-3000-Mobile-V2-13-GHz/m7659vsm7647
If EVE worked before, hardware is not a issue. Minimal requirements didn’t changed for some time.
