I already knew this would be a memorable episode.

Oh I never tried shooting cloth in Mirror's Edge :o that looked cool.

Aside from the "dark to bright area" effect i never liked bloom.

It feels like a cheap way to hide flaws in the graphics, some games uses it way too much.

Great video as always Cam!

Another entertaining video, thanks!


Tress FX is such a goofy technology though... it looks good in a few circumstances but in general it seems to cause hair to stutter and fly all over the place as though it's way too statically charged.  I've heard the effect looks better on AMD cards though, so maybe my Nvidia 660 Ti was to blame...?

I love seeing those fake adverts for hair products lol

These Reality Checks were very good! Good work.

I don't get why motion blur is used to simulate how human eyes gathers information. My eyes can do that by themselves! Adding that to the game, just doubles up the effect, making it seem annoying to me.

Way to give P.C. some love.  This is wonderful.  Even though I already know all these things, I still like reading the articles.  Keep up the good work guys.

The only thing you need to know about motion blur is how to turn it off.

This series was very interesting and informative, however I think I'll stick to console gaming. Keep up the good work Cam, I love Reality Check :)

a series(!!!@!!!) that follows juuuuust this topic, but in much greater depth would be pretty sweet!!!!!


(it would give you direction for several episodes as well)

TressFX Max Graphics. Looks like a promising product, though I understand it will only improve my look in video and not in freeze frames. Is this true?

Just a minor complaint Cam, Max Payne doesnt use Ragdoll effects it uses Euphoria.

This was great, especially that ending! I for one have yet to understand why a game running at 60fps or even MORE still doesn't look as smooth as 60fps should (as compared to a video). I've heard people offer unconvincing arguments of "variable framerates" when I had 10-year-old games never dipping below 100fps on the likes of a 580 gtx or a 7970 on a 120hz monitor and STILL didn't look that smooth (i.e. as a video @60fps).

Tomb Raider looks better without tressfx anyways...

I hate motion blur. Give's me motion sickness.

Reality Check - In my personal opinion this is one of the best shows in the world. Entertaining and informative. Keep it up!

What, no lederhosen? I usually don't like motion blur, but never thought about using it for race

games. Need to try this.

In my opinion, AA is the most overrated effect ever. Lose a ton of performance for an almost non-noticeable image improvement.

@Nikolajj I agree. Specially if you talk about distant objects / scenes. But... in motions I think if you have a low fps, the blur make it less noticeable in fast movement. I usually don`t like either.

@Zombie97 Theses effects is used on consoles too... the different is that on PC you can turn them on or off (change the resolution, and everything else). On console its is chosen by the develop.

@Duckynevada Exactly. If you want to give an example of ragdoll effects, compare Max Payne 3 and GTA IV/V with Saints Row or TES IV or V.

Good video though, but yeah it would have been nice to have a little nod towards the Euphoria Physics system and how much better it is over your typical ragdoll effect.

@DireBane_SXE When you don`t have a really good pc.... I agree. I usually prefer to turn on other options, and let the AA less. But.... its personal taste.

@DireBane_SXE I can't get away with no AA at 27" 1080p.  I need AA or I'll lose too much blood from the jagged edges.

@DireBane_SXE seanwil is right. Doom3, Half Life 2, Far Cry... antialiasing made the playing experience MUCH more aesthetically pleasing.

@DireBane_SXE I can't stand games without AA.  For me, it goes: Resolution>Antialiasing>Other junk like texture/effects/model quality.

@DireBane_SXE traditional multisample anti aliasing (MSAA) is a performance hog and not all titles use it very effectively (games using deferred rendering especially). It doesn't deal with transparencies like trees or grass so additional supersampling is required for that. MSAA is best used for people who have powerful GPUs with spare processing power.


1080p has been a standard for quite some time and the switch to 1440p (and high Hz) has been a slow one. Some 1080p screens are very large (like 24-27'') and have a painfully low PPI number (low pixel density). This makes jaggies stand out more and so MSAA is a way to ''buff'' the resolution and lessen image artifacts that are more apparent on monitors of that size. People are sensitive to a different degree to these things. Some don't notice any aliasing or shimmering (the lucky ones) and don't need any form of anti aliasing.

@DireBane_SXE @shadow580 My old monitor was that, and yes, AA makes a pretty huge difference.

I am now using a 27" 1440p monitor and AA is still very necessary.

@dogman12602 @seanwil545 @DireBane_SXE FXAA blurs a lot though the real benefit being that it's less of a hit then msaa but the quality is where you take the real hit. You guys are right though play at a high enough resolution and you'll be hard press to notice jags or can easily get away with running a small amount of AA.

@dogman12602 @seanwil545 @DireBane_SXE

Typically 4AA of any flavor has always been enough me. 2AA if the performance hit is too great at 4AA.
