Win7 64-bit back to 32-bit. Preformance drop 90%.

[Coldkilla]

I don't get it. I had 64-bit Win7 installed on my machine and was able to run the GFX settings of GTA all the way up 100% on everything. Averaging 36-47FPS. Now I've reinstalled my 32-bit version and even the game-default settings put the game into the FPS bracket of 1-3FPS. Just to hit escape and click the "graphics" icon takes 30-50 seconds.

 

Any reason why this is?

• GTX 285
• 6GB Triple Channel
• i7 920
• GA-Ex58 Ud3r

Fresh format, newest drivers (tried 5 previous display driver versions with same results). Any tips on what I might have missed?

[Weirdo.]

Why in the holy Hell did you downgrade?

[Coldkilla]

Again - multiple games I own have problems (officially and unofficially) running 64 bit and I am frankly tired of the hoops I have to go through with it.

 

As such, I'm not here to debate the pros and cons of 64 bit. Now back on topic

[radioman]

One reason could be because when you downgraded to a 32-bit OS, you lost some memory as even though you have 6GB RAM, a 32-bit OS for Vista and 7 can only recognize 4GB, so the other two GB are not recognized. Like on my Vista laptop for example, I have 3GB, which all of it was recognized by Vista, but when I upgraded to Windows 7, it now says 3.00GB RAM (2.75GB Usable).

 

It would have been wiser to have stuck with the 64-bit version since you have more than 4GB Ram. More than likely, it was your drop in usable RAM that caused the game to go back to default settings, with the frame drop. imo.

If your FPS dropped to 1 - 3 FPS, then the problem is something else, not the OS.

My point exactly. The change is too drastic, considering I can hardly run the game at 30% (average) GFX settings opposed to the previous 100% + GFX Mods averaging my previous FPS.

 

Windows XP32 ran better, so I know its not the OS. The change is too drastic.

You're right, it's not the OS-It is more than likely the version-64-bit to 32-bit version that is causing the problem, since 32-bit OS's cannot recognize more than 4GB Ram, whereas 64-bit can recognize 6+GB RAM. When you downgraded to a 32-bit OS, you lost 2GB usuable RAM, as 32-bit OS's cannot recognize 6GB RAM...

[viometrix]

radioman is partially right. that whole setup you are running is pretty much 64bit only. your motherboards north bridge needs a 64 bit controler due to the triple channel nature. i am suprised you have not blue screen or froze up yet.

 

i personally have not run into any issues with any games at all that run on xp or vista, so i have no idea what you are trying to run.

[Coldkilla]

Well all I know is that I've run 32-bit prior and got 10000x better performance.

If you have a copy of both OS's then dual boot between them. But like someone said, if you're getting 1 - 3 FPS, somethings wrong and it's NOT a software issue.

Try doing a quick OS reinstall, sometimes things get messed up with fresh installations. I have never seen something this extreme, though.

 

Also, some of you people should really stop posting bullsh*t. Triple channel memory access is triple channel no matter weather you're running a 32 or 64 bit OS. If you have 6GB RAM on a 32 bit system you will access to only a slice of that RAM, but the part you'll be using WILL BE in triple channel mode.

I should also point out that with a 32 bit operating system, you only have access to 4GB of your RAM, MINUS YOUR GRAPHICS CARD RAM. If you have a 1GB GPU, then you only get access to 3GB or thereabouts.

To be precise, 4 GB minus allocated PCI RAM, which is influenced by graphics memory, but not equal to it.

Reinstall your OS, now way you are getting this bad performance on a i7 920 and GTX285, of course indeed it seems like an utter waste of resource to be running a 32 bit OS. As mentioned already, your 32 bit OS can only address around 4gb of total memory, so that's at least 3gb wasted right there. At least consider a dual boot, so that you only run the 32 bit for games you do have problems with.

To be more precise, if we are talking about the memory address space that's available to the user programs, that's limited to 2GB while the system itself holds on to the other 2GB. This means that one 32bit app can commit only 2GB of memory space (if we ignore the PAE switch).

Wow I think its pretty funny how a lot of people think its the fact that I went to 32bit. How much RAM does GTA4 utilize anyway? I've seen benchmarks showing only 2.4GB being used... Tack on an OS and thats 3.4 fine, but bring the settings down a bit and I should be fine... However thats not the case.

 

I don't get the assumption that I'm running a full game at 100% settings with 32-bit. No, in fact I am running everything at 30% average with 1920x1200. The change is too drastic for it to be the OS. Also, if its a physical hardware issue... What changed between the 1 hour I had the OS and the hour I didnt?

 

Wellp, anyways - I planned on making a huge GTA4 movie this winter break and damnit if I can't fix this issue I'll just flippin swap back to 64 temporarily.
