Just Cause 2
Just Cause 2 is one of the older titles in our suite and uses DX10 visuals. It's no longer cutting edge, but it's still a lot of fun and can be used to cross-reference older reviews.
Heck, even the little R7 260X can manage an average 32fps at 2,560x1,440.
Per-second examination - R9 270X - 1,920x1,080
Older games pose no real problems to decent mainstream GPUs. R9 270X continues to lead against price-equivalent Radeons and GeForces.
Per-second examination - R9 280X - 2,560x1,440
We couldn't tell the R9 280X, HD 7970 GE and GTX 770 apart when playing through Just Cause 2 - the per-second benchmarks confirm there's little performance difference between the trio.
