Anyone tried yet?

Just wondering if I should bother with the download before I get my new PC :(

As the Win XP was officially dead even before the game come out is not a guarantee.
The game uses OpenGL so, by graphics is possible, however, is only made for x64 processors, if your current computer system is 32 bits, then no.

It requires 64-bit operating system (Vista or better) so no, it won't work on Windows XP.

[i]Works on:
Windows (Vista, 7, 8), Mac OS X (10.7.0) and Linux (Ubuntu 14.04, Mint 17) [/i]

A bit of information, that's not exactly hard to find yourself.

edit: Ah, I see GOG has somehow managed to damage tags.

Just installed, skipped through all the intros, character creation etc. got into the game proper and... boom go figure, it works on my 32-bit Win XP system.

YMMV but ya, that's quite a nice surprise for me as I didn't want to rush buying my new PC.

@DProject I know the sys requirements did not list XP but many games on Gog and Steam do not list XP and end up working on it - and it looks like this is one of them.

Off to play now :)

Nice to know, anyway maybe htis post could be of interest : http://forums.obsidian.net/topic/71503-poe-and-windows-xp/page-2#entry1598919

In resume: Yes, can run in Win-XP (32 bits) not very well tested though, and could be better the (almost exotic) Win XP 64-bits

Steam lists 64-bit as requirement so that's where my confusion came from and neither GOG nor Steam lists XP as OS so I tought it would have 64-bit executable too. Does game come with two executables then as afaik a 32-bit program can't use more than 4gigs of ram even with large address aware enabled? If not I suppose the recommended 8 gigs ram is just so that game has 4 gigs available for certain.

No. The game doesn't deal with memory too well so it will crash about 1 hour in. It runs perfectly on an XP system until the point that it runs out of memory. Pretty strange as you are basically giving it 64 times the memory needed to run Ice Wind Dale -- but that's still not enough. Sad that they couldn't figure out how to make this retro game run in 2GB of application memory that 32 bit XP provides. Really sad. Nope. It just runs out of memory and dies about an hour in. You can keep trying to play but it will randomly crash on the loading screen when you move from area to area.

I'm sure it's not that they couldn't figure it out.

It's that they didn't bother trying.

And really, why would they? It's 2015. My phone has two gigs of RAM. The cheapest PC Wal-Mart sells, at $129, comes with four gigs of RAM and Windows 7. (Though I see they do have a $199 laptop that only has two gigs. And that PC's video wouldn't handle the game, but that's a different issue entirely.)

I don't think it's reasonable to expect a developer to optimize for hardware so old that bottom-of-the-barrel PCs outspec it. As for the OS, not only is Windows XP end-of-lifed, the OS that replaced it AND the OS that replaced the OS that replaced it are out of mainstream support.

It does suck when a game comes out and you can't play it because you're stuck on old hardware or software. I had the same issue for years - I couldn't upgrade my Mac past 10.6 because I needed Rosetta - but blaming the devs that software needed a newer OS or more hardware than I had didn't help.

Good to know, my main reason for "not get it" just crumbled down.

Any crash or other problems so far?

Yes it does work. Ah...mostly. The issue is one of not enough allocated memory. For some reason our friends at Obsidian began to make the game for XP and when problems with memory crashes crept in they just left these problems unfixed and changed the minimum requirements. The game will run just fine, but when you go to a large map (like a city) you may get a memory crash on the loading screen. If you restart the game and try to load the map fresh (right after starting the game) you have a good chance of being able to continue. I'm experimenting with trying to finish the game on XP as a challenge. So far I'm over 20 hours and I'm still able to continue. I haven't had a crash in quite some time because I'm working out of my keep (which never crashes) rather than one of the cities (which nearly always crash). I'll keep everyone updated. I'm kind of sad that Obsidian didn't put in the tiny bit of extra effort to make it work completely on XP. Good old XP provides the game over 60 times the memory required for IceWind Dale, which to me, should be enough. Guess not.

It does work. Sort of. The application itself isn't 64 bit at all. The reason it requires a 64 bit opsys is because it hogs up way too much memory and crashes. Why a retro game of this sort needs more than 2 thousand megabytes of main memory is beyond me, bit it does. (Which, by the way, is over 60 times what Icewind Dale required!!)

I've been trying to play through it as a challenge with 32 bit XP and I'm about 20 hours in and I haven't hit a hard stop yet. I suspect when I go to the big city I'll hit that hard stop, but so far I've been able to keep going mostly by working quests out of the keep (which is a relatively small map compared to the cities). It crashes on the load screen with a memory fault is the actual problem. So far I can continue by simply saving before leaving every map (especially moving to a city) and just restarting the game, reloading, and transitioning to the map right after the load (which has always worked so far). We'll see. It is nice to be able to manually control updates with GOG as I suspect Obsidian will further break XP in the updates (by simply making the game bigger). We'll see.
