ATI Radeon HD 5450 On Linux
Right off the bat we see the ATI Radeon HD 5450 run well below that of the NVIDIA GeForce GT 220 or even the previous-generation Radeon HD 4650 -- either of which graphics cards can be found for just over $60 USD.
With Warsow the results are much the same story except for the GeForce GT 240 running faster than the Radeon HD 4650 this time around.
OpenArena will run just fine on any modern graphics card with a proprietary NVIDIA/AMD driver, even the Radeon HD 5450, as it is rather CPU limited.
