I guess some people are just always pessimistic.
Once again you have NO EVIDENCE that games aren't advancing graphically. You keep talking about short term windows like from 08-12, but you ignore the fact that there hasn't been a new system developed during that period. What you seem to not understand is that PC gaming is
NOT ubiquitous. If there isn't a pool of millions of potential buyers, then no one is gonna spend $100 million to develop a game that only 1-10,000 people might buy.
And even if PC gaming was ubiquitous, there isn't a uniform system in which a developer can work on so he can maximize the graphics. Developers are instead gonna build their games around systems which are the most widely used (that is the 7 year old consoles) and just port the games onto PC. It's the reason why games like Uncharted on PS3 still look as good as most games on high performance PCs. Sure most PC games look better, the key however is that the game wasn't built to maximize those specs. So its wrong to extrapolate that because PC games haven't progressed tremendously in terms of graphics in the last 5 years, that a wall has been hit in terms of graphics.
Breh these last 4-5 years have been the slowest in terms of big leaps we have made in terms of graphics. The PC really hasn't been the "lead" platform in terms of the mainstream since the mid 90's so your whole argument is flawed from the jump.
Just look at what I consider to be the milestones from the PS2-Current Era...all platforms.
So lets have a little breakdown of games that I remember making a leap in terms of graphics.
2001 - Max Payne 1 (PC) - MGS2, ICO, and FFX on the PS2 - Halo on the XBOX
2002 - Metroid Prime and Resident Evil Remake on the GC
2003 - Zelda Wind Waker, Max Payne 2 on the PC (still holds up well)
2004 - DOOM 3 and Half-Life 2 on the PC, HALO 2 on the XBOX
2005 - Resident Evil 4
2006 - Oblivion
2007 - Crysis...nothing else was close
2008 - Dead Space, MGS4
2009 - Batman Arkham Asylum on the PC, Uncharted 2
2010 - Metro 2033, Heavy Rain, Mass Effect 2
2011 - BF3, Uncharted 3, Skyrim, L.A. Noire
2012 - Far Cry 3, Halo 4
Now lets look at 2007 to now. Crysis holds up to anything else out there and is going on 6 years. Like I linked before, Batman Arkham Asylum was pretty incredible on the PC...that shyt looks amazing TODAY compared to other games that have been released...even Skyrim and Far Cry 3. Oblivion to Skyrim is another example. No doubt that Skyrim looks better, but I don't think the difference is a major step up compared to what a 5 year gap used to mean in the past. Hell for a while DOOM 3 looked damn good given its age.
Crysis came in and crushed the buildings thats the last game that came out that people were like

my card can't handle that...AT ALL. Not even the highest NVIDIA card could bench it. Metro 2033 was a leap with its tesselation, phsyx, and after effects, but I don't think it looks THAT much better than anything else to tell you the truth.
