It is not Java, nor anything like that. MC is native and is written entirely in C++ (like much of OSX itself is). It is not written against the AppKit frameworks, however. JRiver built their own cross-platform framework entirely in C++ (which is no small feat, I'll add).
For the record, 1920x1200 is a very low density for a 27" display. You're probably seeing differences in how anti-aliasing works through AppKit vs. JRiver's display framework. They could possibly do a better job, but...
At that pixel density, all fonts have blatant jaggies. You can hide them by blurring them (with AA) but that makes them fuzzy.
1) Ah! Thnx for the info - interesting - it does have a little bit of a Java feel - then again java itself is also a C/C++ cross platform framework and platform... but indeed not a small feat!
2) my bad - 21 inch at 1920x1200, not 27! - while not 4K or Retina resolution, my whole point is that is very noticeable against other apps in the same computer and monitor - and that difference is making my brain and OCD go crazy, hence the question to try and fix that and make it look the same as other apps in the same computer and monitor. Pls be assured I am not comparing against retina or similar displays - I just wish JRiver would look the
same as the other apps *again, in the
same computer and monitor*... all those other apps confirm that it could look better...
3) That said (and to finish on very positive note) otherwise very impressed with JRiver - sound quality is great - handles my hires file effortlessly... and is a single app. No issues supporting my Schiit Audio system. And it handles video to boot! Like I said, very impressed.
Thanks again!
