Quick question, how many of you play this game using a tv as a monitor? what are your resolutions in game settings at and what size tv screen do you use?
I used my 32" for months running at 1080p. There's really nothing different than using a normal computer monitor other than the size. Now if you have a 4k tv or a 3D tv that may be a whole different story.
Just depends on your CPU. I run on a VIZIO 32" 1080p she's beautiful. I have a i5 4670 and a HD Radeon 7950 3GB. So if you have that power to run it good your alright. I get about 80-110 FPS. All settings maxed and ATI AA and other settings pretty high.
Physical size of the monitor affects in no way for the performance. Only thing that counts is the resolution, that is how many pixels there is for the GPU to render. As said, it doesn't much differ using a TV as a monitor. Only thing that one might notice is incresead input lag, which can be quite high with many TV sets. It is a property that isn't that big deal with TVs, although one should think that popular consoles would have changed this also. Increased input lag might not be that big of a problem with something like nr2003. Also, like with monitors, some TVs produce it more, some less.
