Raspberry too slow?

Thu Mar 24, 2016 9:24 am

I posted questions about the performance of my Raspberry Pi before, but I didn't got a clear answer. I don't mind it being a little slower then an average computer, but it's just a little too slow to be useable in my opinion. The reactions to my questions before where promising. So I'm afraid there is something wrong with my Pi or my configuration.

I DID read somewhere that Quake III runs on Raspberry Pi.
Yes. I run that also. It's surprisingly fast and smooth. Definitely very playable.
I think you'll be shocked by the RPi3B, it's got more MIPS per square centimetre than ANY other computer I've ever used. (Especially compared to my 2012 vintage smart phone.)
I used System Profiler and Benchmark to show you some info. Is there anything wrong, as far as you can see from this info?

Please keep to the original threads, don't keep raising new threads basically on the same subject.
