Under the risk of adding noise here, I tried this apitrace on a intel HD4600
(haswell). I got several visual artifacts (in addition to be really slow),
getting several performance related debug warnings. For example, at the initial
phase, where it is mostly compiling shaders:
10202: message: shader compiler performance issue 478: SIMD16 shader failed to
compile: FS compile failed: Failure to register allocate. Reduce number of
live scalar values to avoid this
And then, when running the log and the menu, messages like the following:
327430: message: api performance issue 1506: Scanning index buffer to compute
index buffer bounds. Use glDrawRangeElements() to avoid this
3836043: message: api performance issue 1553: GTT mapping a busy miptree BO
stalled and took 1516.024 ms
Anyway, probably this would need to be taken with a grain of salt, as usually
games detect hw capabilities in order to know what to use. Probably it would be
worth to try the game on a intel hw (unfourtunately I don't have access to that
game).
