So what's it supposed to improve? Gotta thread to link to that will explain it?

[Smokeyjedi]

Well, worst case scenario 64 bit mode flops and we all flip the switch back to 32 bit as if nothing happened. sounds like a plan. A thoughtout plan. What is going on inside PGI lately.....

[GentlemanBryan]

Good job PGI! I'm ready to purchase a mech pack to support you guys.......

What does 64bit get us?

[Felio]

Cool, now enable the occlusion culling already in the engine and triple performance on low-end systems.

Still waiting (since beta) for the client to not need UAC elevated permissions to run.

I am by no means an expert, but essentially 64-bit lets you use more of your computer, especially multi-core usage and RAM. Here is a basic (though lengthy) explanation of it: http://www.howtogeek...-bit-windows-7/

64bit allow MWO to use more that 4GB of memory which indirectly increases performance because it allow the app to cache more stuff into RAM. The following shows the relative speed of accessing data from various type of memory by translating the times into seconds so you can get an appreciation for the difference in scale between the numbers:

1 CPU cycle---------------0.3 ns--------1 s
Level 1 cache access---0.9 ns--------3 s
Level 2 cache access---2.8 ns -------9 s
Level 3 cache access---12.9 ns------43 s
Main memory access---120 ns-------6 min
Solid-state disk I/O------50-150 μs---2-6 days
Rotational disk I/O-------1-10 ms-----1-12 months

As you can see, putting more stuff into RAM changes the access time to minutes from days or months, relatively speaking. This mean that the app spends less time waiting around for data so it should make things go faster.

Can we have an update on SLI performance scaling and issues?

Would love to put my 4 Nvidia Titan Blacks to good use.

Cheers PGI!

Send one to me. I'll use it. I promise!

Wait, that's not what you meant is it?

Woot! Does this mean I get to use both of my quad core xeons or just that I get to useall four cores on one now? Each one has 8gb ram, so maybe using 2 cores per if it's limited to four threads?

[R E T I]

Thanks for the link Cimarb. It helped me understand 64 bit a little more then I already knew.

The text has since been adjusted a little from the original wording, but we want to stress that this is currently an experimental implementation of the 64-bit client.

Your house/apartment/dwelling probably won't explode, but there might be some issues with the client here and there.

Does this mean AMD owners are going to get the shaft again?

If you were to figet with your system you could already use those 8 cores. but now MWO wont use a maximum of 512MB per core for a lame 32bit memory max. instead allowing all your ram to work as win 7(+) 64bit intended . unleashing a bottleneck im hoping........

I downloaded directx from that page but its saying 9c only and 2009 files. Anyone know why? Shouldn't it supposed to be newer?

Yay, finally going to get some use out of having 16 GB of RAM!

[VictusRhul]

I ran the patch and the option does not appear in the gear box. I uninstalled the whole thing and downloaded the client from the web site. Reinstalled clean and patched. Still no gear box option to run 64 bit. Any clues? I know this is xperimental but just wondering if there is something else I need to do?
Both the Xdiag and C++ installs said what was loaded is current or newer than what was downloaded.
Any advise would be appreciated.

I have not been on the PC side of things for a while, but if I remember correctly here is how memory works in Windows

32 Bit:
Max of 4 gb of memory used by the OS + all process
However, you graphics card counted against that memory total, so if you have a 1 gb graphics card you would only use 3 Gb for the processes

64 bit
Home Basic- 8 GB for OS plus all processes
Home Premium- 16 Gb
higher than that 192 Gb

HOWEVER,

when running 32 bit apps, that process is limited to 4 Gb of space. Unlike a 32 bit OS, the graphics card does not count against that limit as long as you have more memory. In addition, iother 32 bit processes (OS, TS, Firefox, etc) can each use 4 gb of space, and 64 bi process can use the entire memory space. this means the 4 Gb is not shared like a 32 bit OS. For this reason 8Gb minimum is your best bet for a 64 bit Windows OS

when running a 64 bit app, the process can utilize all available memory. up to the limits above.


What this means re: 64 bit MWO.

If you have >4Gb memory and a 64 bit OS, AND you are not using all the rest of the memory for your graphics card, the Os, and other process, you should see more memory utilization.


Example: (numbers are made up, but not unreasonable)
8 Gb x64 machine:

Graphics card mapping: 1 gb
OS: 512 Mb
TS: 50 Mb
AV- 25 Mb
other apps- 125 Mb

This leaves 8Gb -1 Gb - 750 Mb = 6,25 Gb free space.

since MWO runs as a single process app,
32 bit MWO can only use 4 gb of the free memory.
64 bit MWO can use all 6.25 Gb of the memory

I tried to install Visual C++ 2010 from the link provided but it told me a newer version is already installed. Any reason why you aren't linking to the newest version? Will it cause any issues?

chances are that is the newest version that they release and the rest are patched. You probably have all the patches so its not necessary. If you're running windows then you already have the package. That is mainly for people running other OS's like linux or OSX that don't automatically download those as part of the native OS

64-bit users running low-spec machines may experience performance issues if attempting to run the 64-bit client. We recommend that those users stick with the 32-bit client if they experience any issues.

Very interesting. This is counter to my experience with 64-bit vs. 32-bit apps in general. Looking forward to giving it a try when I'm home from this stint on the road.

Long time in coming though, well played PGI.
