Vista vs. XP Game Stability and Performance

boyko.at.netqos writes "HardOCP does a side-by side comparison with a battery of games to check stability and framerates in Windows XP and Windows Vista. In addition to the lowered framerates in Vista, they had stability issues in Need for Speed: Carbon and Prey. From the article: 'For some titles, especially Company of Heroes and Need for Speed, we saw dramatic framerate discrepancies. What's more, both of these titles have recently released patches! Other titles showed a slight, but essentially negligible difference, such as BF2142, World of Warcraft, and Prey. Really, there was only one instance where Vista was able to pick up a few more frames than XP — World of Warcraft at greater than 90fps, where the human eye can't even see the difference. To see this overall trend against Vista is very interesting and makes us wonder as to the cause.'"

Useless comparison

[GreenEnvy22]

As discussed in the actual article, this review is useless. All it shows is that Nvidia systems perform much slower on Vista then XP. They then go on to conclude that Vista must be slower then XP. It's quite well known Nvidia's drivers for Vista have been absolute trash, while ATI has been on the ball. While Vista will be slower for most games even with ATI hardware, the difference is far, far smaller.

It is not useless if you have a 2gz P4 Nvidia system and you wonder what would happen if you "upgraded". The article was interesting had a wide range of games and had Christmas tree graphs that showed how lame Vista is in game performance and how little you get for your money by "upgrading". It is fair to say that on newer computers you get about the same performance as your old computer so you will not be losing anything. I cannot for the life of me think about anything worth upgrading to vista for a home PC yet. It is not any safer and is more annoying and has the same printdriver scanner support as Ubuntu. When I upgrade my work computer it will be to Ubuntu and my gameing rig to an DS and PSP duct taped together back to back.

Lower frame rates = higher security

[Cathoderoytube]

I think the people doing this test should really have a look at the vista manual. If they did they'd know the OS was designed to block suspicious looking frames from the games we play to keep your computer secure. This generally means a slight performance hit. But hey, if you're willing to shell out hundreds of dollars on upgrades for an OS, what's a few more hundred to buy an even new video card that'll allow you to play games with performance comparable to those on a machine running XP with less powerful hardware?

Frame rate perception

[Mprx]

The human eye is an analogue device, and does not see in frames. Because computer games generally do not feature realistic motion blur, we can see a benefit from increased frame rates well above the 72fps which would be sufficient with perfect motion blur. Accurate motion blur can be thought of as "temporal antialiasing", analogous to the spacial antialiasing supported by modern graphics cards.

Re:Frame rate perception

[MotherMGA]

What the article does not state is that there reason for such slowness is that behind the game, Vista is poping up the message:

"You are attempting to refresh the screen. Cancel or Allow?"

Re:Frame rate perception

[SighKoPath]

Motion blur is purely an artifact of recording devices.

That is why recording devices can get away with recording at under 30 frames per second. For example, movie projectors display at a mere 24 frames per second, with no perceived problems! Good luck playing any 3D game at that frame rate without noticing. However, if the game had motion blur, it would look just fine at 24-30 FPS.

The big question is, is this even practical? To me, it seems that running at the higher frame rates is easier than correctly rendering motion blur.

LCDs are worthless for any game that's dependent on fast reaction, such as first person shooters. Modern first person shooter design is moving towards deemphasizing twitch, for example by adding autoaim and weapon spread and slowing the game down, but play an oldschool fast FPS like Quake 3 on a CRT at 120Hz vs. an LCD at 60Hz, and you'll see it makes an enormous difference. Not only is the perception of smoother movement important, but latency too. With an LCD, a frame is buffered in the graphics card for 17ms, buffered in the LCD for at least 17ms, and then displayed over at least 5ms. With a CRT running twice as fast, the frame is buffered in the graphics card for only 8ms, not buffered in the CRT at all, and displayed over an average of 4ms (the top of the screen almost immediately, and the bottom after just under a whole frametime). That's 38ms added latency for a top of the range LCD, and 12ms added with a moderately good CRT (truly fast CRTs will do 200fps or more). A slow LCD can add 100ms or more (see "LCD input lag" discussion). Human visual reaction time is about 200ms to 250ms, with the highly gifted going slightly faster, and those tired or under the influence of depressants a lot slower. To be competitive at a twitch-heavy FPS you'll need to be reacting around 200ms (one reason why twitch is deemphasized now, so player genetics is not so important). The additional 26ms latency from choosing a fast LCD over an average CRT is a significant chunk or your reaction time, and enough to affect your average success rate in twitch-vs-twitch situation.

My (older) games won't even run on Vista

[Dr. Manhattan]

As I've said before, Vista has been horrible for games. And these aren't new, flashy, supreme games. These are games from a few years back, that should fit comfortably on the hardware, and I'm not cranking up the resolution or the detail or anything. The hardware I refer to: AMD Sempron 1.8GHz (allegedly equivalent to a 3GHz+ processor), 1GB RAM, 80GB disk, Geforce 6150 integrated graphics. Not (at all) a speed demon, I know, but I'm not asking for miracles. Look at the games I'm trying to run:

• Aliens versus Predator 2: Runs slow, audio is skippy. 90% of the time fails to launch properly.
• Tron 2.0: Slow, skippy audio. Seems to always launch into the game menu, but firing up a save game crashes the program much more often than not. Vista doesn't crash at this point, but it takes about five minutes for it to recover.
• No One Lives Forever 2: Actually runs okay, much of the time. But about 20% of the time it won't launch a saved game, it instead crashes to the desktop. At least it's faster than Tron 2.0 at crashing, and a relaunch usually (~90% of the time) is successful.
• Freedom Force: "This program is not compatible with Vista."
• Freedom Force vs. The Third Reich: Seems to run as well as NOLF2.
• Half-Life, Half-Life 2: Worked for the limited testing I did. HL2 is quite slow and jittery on this system, though. (Not totally surprising, but still...)

So, really, only two games actually run well enough to bother with: NOLF2 an FFvTTR. (Oh, okay, HL2, Blue Shift, Opposing Force work all right.) Obviously I'm not a huge gamer, and I know this is a low-end machine, but oy. My previous experience was with XP on a dual Athlon MP 2600+ system (2GHz real clock), 1GB RAM, GF5700LE card. A better system (and a lot more expensive when I got it four years ago) but not that much better.

How to upgrade XP to Vista for free:

[Opportunist]

1. Download some free theme that looks like Aero. Watch out for malware.
2. Remove half your ram.
3. Clock the CPU down a few notches.
