Ive been noticing that when I play UT that after a couple of maps my system starts to get real slow, I usually have the task manager open on my 2nd monitor and it seams that the memory usage just keeps going up and up. Basically I was wondering if anyone else had this problem. I suspect its maps not being cleared from memory after the game switches (average seems to be about 300-400 MB added after each map)

System specs? Might be a case of extraneous textures and meshes staying in RAM... how large is your page file? Is it on a seperate partition, or at least on a different drive than your UT folder?

I let Windows manage my memory and don't have any problems like this. I am curious to know what you find out.

Processor: AMD 64 3700
Memory: 1GB (pc3800 / 400mhz) RAM
Video Card: eVGA GeForce 7800
Virtual Memory: 6 of 7 partitions on 5 drives with max virtual memory

Windows and Unreal are installed on a raid 0 array of 3 SATA Hard drives (no virtual memory allocation on that partition)

I doubt its my system setup although I have been thinking about getting 2 GB of Ram since the photoshop files for my last couple of skins end up at like 75-80 MB and to run photoshop with unreal ed or upaint (for previews) things get a bit slow then.

I'm usually ok playing UT for about 4-5 maps or when memory usage is at about 1.3 - 1.5 GB (I run high details with a resolution of 1024x812 or somewhere around there)

System:

MS Windows XP Home Ed. V2002, SP2
Intel Pentium 4 CPU 3.21GHz (ACPI\GenuineIntel_X86_Family_15_Model_3/0)

Intel 82801EB Ultra ATA Storage Controller (30gb Ultra ATA on IDE 1, Secondary 4gb non-ATA drive on IDE 2)

1.00GB RAM with Virtual Memory managage as such:
Paging file located on primary IDE controlled device
File size manually set to 1536MB for all drives (to free up the processor from looking all over the place and to give it room to work).

I run the game on a e-GeForce 6800 DDR 128mb @ 8X with a resolution of 1024x768 with all bells and whistles turned on.

 


I am running like this, don't know if it will help, but note that the paging file is on the primary IDE device where my game and OS are also located. I have had zero memory related issues.

I have heard that RAID can be a bottleneck sometimes due to differences in MB engineering. My dealings with it made it seem as though it was great for storing and retrieving data, but horrible for response time due to MB piping and/or processor capabilities. It actually has to shove tons of data from that redundant array of independant (or inexpensive) disks all down the same lanes through the Skuzzy, then there is the software involved to include the expanded FAT for all that information. They can get pretty fast, but common sense would say that all that traffic will sooner or later have a wreck.

Never thought of it in terms of 'memory overload' because I never used it for something like UT. I especially wouldn't have considered all the different virtual memory allocations throughout the system. I used it more or less for data storage for FTP / IRC stuff back in the day.

If it were me, I would put one of those HDDs (preferrably the one with the OS on it) on your primary IDE, then eliminate all the virual memory on so many drives and partitions. Then put the paging file on the IDE drive if it is big enough to handle 1536 or some such. You may be having purging issues due to miscommunication with all these different drives and partitions. The easy route would be to cram a ton of ram in there and just let your processor grind it out.

Dunno, more of a guess than anything. But it sure sounds good.

Why would you need to set virtual memory on more than one drive or partition. You only need one as far as I know of.

As someone who has dealt with OS internals and RAID for several decades, I can give you some details here...

When dealing with non-RAID, you generally put portions of your swap on different drives so that you can do I/O to multiple drives at once. You also, given the chance, should have the portion which resides on your more heavily hit OS/software drive set to a lower priority, so that it is only used when you absolutely need it, and you have your higher priorities on your higher speed drives.

Now, with RAID, things are not as straight forward. First, if three drives are in a RAID plex, you treat them as a single drive which is probably larger, and may be faster than any of the component drives. But if you can carve off portions of those drives and use those portions for swap, well then you treat them separately, but have to worry about the impact on the RAID plex itself. The complexities continue from here, and can get to be so complicated as to make your head hurt.

@Spacey/Chyster

Thanks

Going to try setting it with no page file on the Raid drives.

Probably going to add Ram next paycheck though.
