Results: Grid 2
Grid 2 won’t embarrass the owner of a cheap graphics card, but it will cause enthusiasts who combine a higher-end GPU with mid-range host processing or system memory to chase bottlenecks. Overclocking solved both limitations in my $1600 PC, while the Radeon R9 290 in Don’s $1200 PC appears held back slightly by his PC's DRAM bandwidth limits.
Grid 2 isn’t a great game for identifying enthusiast-level graphics bottlenecks, but it is good for diagnostics. It’s also pretty fun to play.
The harder you lean on graphics, the more Grid 2 demands of the rest of your system. The $1600 and $1200 machines both appear bottlenecked using the Ultra graphics preset at 1920x1080 and below, at least until they're overclocked. Paul had bigger concerns with the prowess of his R7 265, yet still managed to push over 50 FPS at his target 1920x1080 resolution.
