F.E.A.R. Performance

F.E.A.R. is a very GPU intensive game, and playing at more than 1600x1200 just won't be an option with anything less powerful than the 7800 GS. Again, the 7800 GS performs nearly at the midpoint between the 6800 GS and the 7800 GT.

When enabling AA under F.E.A.R., it seems that the 7800 GS is a little more resilient than the 6800 GS. The X1800 XL still remains ahead of the 7800 GS, but neither are really playable above 1280x1024.

    Sorry, most of our tests were run with AF enabled (8x in most cases).

    The only test that did not include AF was the Splinter Cell: Chaos Theory test with out AA (the 4xAA test also included 8xAF).

    Thanks,

    I'd like to see some benches of the 6800GT or 6800Ultra(preferably the ultra) included just to see how the G70 architecture compares to the Nv40 in terms of "improvements"

    6800GT is almost exactly like 6800GS.. so it's a waste of time... most (if not all) reviews of the 6800GS would have already taken care of that comparison
  • Jep4444 - Wednesday, November 23, 2005 - link

    the thing about the 6800GS and GT being similar is that they arent uniformly similar, they traded off a few benches and overall the GS is slower

    what i wanted to see was the fact that they have the same pipeline setup and the 7800GS is clocked similarly so i wanted to see how much the G70 architecture is actually improved

    One thing I've been wonderingabout your benchmarking: Some time ago there was a question of whether average framerate should be the sole basis for comparison (IQ issues aside). The argument was that if a card really chokes on certain parts of a scene, having 10% higher average framerate wasn't exactly great. Would it be possible to do a graph of the frames so we could see how much they vary? Or is this not really an issue today?

    It does matter to some extent, but it is very difficult to do a good job of representing this data. Graphs of instantaneous framerates over time is next to useless in our opinion. Its too hard to actually tell what's going on and way too difficult to properly compare a number of cards without totally destroying readability.

    I keep voting for boxplots but there's still some debate about whether teaching our readers about statistical analysis is a good idea :-)

    I think something that can show outliers, min, max, lower and upper quartiles, and median in as much space as a single bar in a bar graph gets my vote as a good thing. The huge problem is that our graphing engine doesn't support anything nearly this robust. We have been trying to augment our bar graphs with some line graphs generated using a spreadsheet program to show resolution scaling, but I still haven't found a good easy way to generate nice looking boxplots.

    Anyone tips?

    Boxplots are an EXTREMELY useful idea, especially the lower-quartile framerate. In fact, the lower quartile may be more useful than the average framerate.

    The lower quartile shows you how smooth the game is in the "slower" half of the time -- which makes or breaks a game's playability and enjoyment.

    Suppose card A averages 60FPS, but the worst half of the time it only averages 20FPS (lower quartile). Carb B averages 50FPS, but is more efficient in relatively complex scenes -- 35FPS lower quartile. Most likely, you want card B, despite its lower "average" framerate. What good is card A when its best 50% of scenes average 100FPS while its worst 50% average 20FPS? A better choice is probably card B, which might average 65FPS in the best 50% and 35FPS in the worst 50%. But average framerates don't show this!

    Posting min and max framerates (box whiskers) is useless, since they will be meaningless (and probably random) freak outliers. Min SUSTAINED framerate is good, and it happens to be closely related to the lower quartile number.

    I reckon if you started to introduce boxplots alongside your standard graphs, readers would catch on pretty fast. People who want the extra information will take the time to work out what it means, and people who don't care can just look at the standard graphs. Or just stick a massive arrow pointing to the mean and leave the rest of the diagram a little more faded.

    Maybe you could make the boxplots appear instead of the regular graphs on mouse over like you do with some of your IQ comparisons?
  • DerekWilson - Wednesday, November 23, 2005 - link

    that would be awesome ... the big problem is making the boxplot though.
