Massive, borderline unacceptable, performance diff between XP/Vista

Recommended Posts

...either that or some serious bug is fucking up my performance.

I'm running Vista 64, with an e6850 @3.3ghz, 8gigs of ram and a 4870x2. Performance has been complete shit in the benchmark that comes with the demo, I then proceeded to do a test with a member of another forum who is running the same CPU but at stock speeds and windows XP.

Setting everything to the lowest possible setting, and visibility to 500m in order to make this about stressing the CPU, the benchmark came back with an average of 48fps on my system and 83fps on his.

This is ridiculous, especially since I really want to buy the game but refuse to do so until this can be cleared up.

Anybody??? I tried -winxp and compatibility mode.

Nothing.

In my experience, XP64 is way better than either Win 7 64 or Vista 64. There are obviously some problems there with RAM detection, driver compatibility etc that need to be ironed out.

I can't play A2 in Vista/Win 7 after playing in XP64, it's like night and day. I'm sure it will all get fixed but for now Ill stick with XP for A2.

8 GB of ram has issues with this game. There's a few threads about it on the first few pages.

Theres issues across all the formats.

Much bigger issues in the newer OS (Vista/Win7) in my experience (and I am running all 3). XP is virtually flawless. I still see the odd white head and there is the odd hitch but it is totally playable.

Vista/Win7 are awful (for A2 and in my experience) and I played around with them a lot before I gave up and installed XP64.

XP is far from flawless...theres fps spikes,lagging,stuttering....AI going awol,black screens in coop.My point is its not down to a specific OS.....look through the forums and it applies to all OS's....its the game and BIS need good confirmation thats its across all formats so everybody gets the fix in the next few patches.

Not in my experience. I've never seen anything that you mention in XP (vis a vis performance), EVER.

The performance is fine in XP for me. As for the AI etc, we aren't talking about that (it needs work), we are talking about performance.

I've tested it across several machines and 3 different 64 bit operating systems. I have no real performance issues with XP64. I can't say the same for Vista or Win 7.

This isn't what I've "read in the forums" from people who think their 3 year old hardware should play the game at 1920 x 1200 @ high detail. These are my own experiences through literally hours of tinkering with different hardware and operating systems.

I've tested it across several machines and 3 different 64 bit operating systems. I have no real performance issues with XP64. The performance under win7/Vista is not good for several reasons that I (and others) have detailed in other posts.

Wow were did you find the time to test all that?...do you have any results and comparisons?

Ive been tinkering around with it since May 19th and as for results, the result is that XP plays the game way better than Vista/Win7 (again, in my experience). There is no way for me to transfer the results (in a viewable form) to the forums.

For example, ArmA2-Mark across all platforms returns roughly the same numbers +/- 400 using the same systems/settings with different operating systems.

These results are deceptive as even though the numbers are the same, the game plays horribly under Vista/Win7 and is nearly perfect under XP64.

The best I can suggest is to try it for yourself. Seeing is believing :)

Ive been tinkering to with the german version and the english release and its not my hardware or my OS....it can only be a lack of optimisation and a lack of graphics driver support....its a spitting image of when crysis was released.

I haven't tested under XP but performance on almost all games (at least one's that utilise DX10 shaders) is better under XP, but at a sacrifice of quality (directX9 instead of 10)

The game plays perfect for me under Vista(32bit) and under Win7(32bit). I tested under Win7(64bit) as well and the game ran terrible with a few crashes, but I put that down to Win7 being new and 64bit not being the most trusted of things.

As a side note, Win7 uses an emulation method to run non-64bit games, i,e; Arma 2. It's a virtual emulation so you'll never get pure results.

This is going to end up being a problem for BIS because 64 Bit Win 7 is going to be "du jour" in just over 2 months (especially among gamers) and I dont see a lot of people running a 32 bit OS just for A2. Further, I notice the same hinkey performance under Vista 64 and that has been around for a few years now.

As I've said before, the only game I have any trouble with under Win 7 64 is A2 (I currently have about 30 games installed).

I'm happy to run it under XP64, but that wont be everyone's take on the situation come October.

The 32 bit OS is becoming a thing of the past, especially with the base i7 config running 6GB for optimum performance. I sincerely thought that A2 was designed with these things in mind. Time will tell.

It'll be fixed soon enough.

In the mean time, I've heard a good option is to rename Arma2.exe to crysis64.exe (to inherit the Crysis 64 bit settings). I have not tested it myself but it may activate fade so keep and eye out and revert back to arma2.exe if you have an issue.

One side note on the issue, I'm sure it's not actually BIS' fault but the fault of the Win7 OS as whenever and issue like this arrives, Microsoft usually release the fix patch. That said, remember that even though Win7 is currently in RTM candidate it's still not final release as they released build 7100 and shortly after there were another 4 builds that fixed a lot of issues, so I wouldn't blame BIS for the problems but more blame that Win7 hasn't been updated to handle a new game system.

I've tried everything in Vista 64, but the main thing that I can't get rid of is the stuttering around high concentrations of buildings. In XP64, it's fine. In Win7 or Vista 64, it's awful.

I'm sure it will get fixed, and I'm happy to play in XP64 until then. It's one of the reasons I keep an empty drive in this box :)

Side note - It happens on Vista 64 as well, so it's not a case of blame Windows 7 or the 64 bit OS as it runs fine on XP 64.

Secondly, out of 30 games that I am using under Win 7 (some old, some new) I have no problems except A2. I'm not really "blaming" anyone as I can play the game just fine under XP but it would appear A2 needs some fixing with regards to large memory configs, SLI, i7 (specifically Hyper Threading), 64 bit Vista (and eventually Win 7 when it is released) etc.

Again, no doubt they will get fixed (as many of the same problems did with regards to A1)
