Doom 3

Let me know if this works guys.

you can do the same thing in ut2004. i havent seen any increase. if you try you should to 64 or 128.

From the thread:

Does anyone know what this actually does? I'd rather not mess with settings just to get a performance increase when in actual fact it could be degrading something else.

I tried googling and didn't really turn up anything.

for doom 3 or ut2004

I saw that last night at gamespot forums:

Several people had concerns about the memory runny too hot with this mod. They recommended using heat spreaders on the memory.

Is this a valid concern?

[TwoRails]

It's no real concern. Using memory is just that, using memory. Just think of all the folks crunching home movies without a problem.

the thing about heatspreaders is hog wash...i did the mod and im running 250FSB...all without heatspreaders .

Getting back to the tweak, I found this in one of the threads:

If it is indeed similar to hunkmegs in Quake 3 based games then it should be set according to your RAM (2:3 is the popular value). It's the amount of memory allocated to the game.

The more I look at the cfg file, the more I think that all that tweak does is set a portion of RAM aside to be used for textures. When texture are stored the RAM, basically, it is a cache; much like a doctor's waiting office. One texture gets loaded, another one gets bumped out to make room for the new texture. By having more waiting chairs, it reduces the need to keep reloading textures that may be used multiple times.

If you don't need to load any textures off the HDD, and just refer to the RAM, this eliminates the delay of having to load and reload texture files.

Well, I gave it a shot and played it for a few hours and came up with no problems. I didn't really notice much of a real-world difference, but for those of you who care about FPS, it looks like it went up about 5-15.

I tried it as well.....seemed to boost performance a bit. I haven't played it for hours to see if it will overheat anything yet.

It worked out great for me in doom 3, but didnt see much of a difference in UT 2004. Before i was having slowdown in 640x480 Rez at med detail on Doom 3, now i can run high in 800x600 with almost no side effects, this has made me very happy
Also, when i looked at my cachemegs, it was set at 20 by default. Why would id software set this so low, considering the machine min reqs are so high? Oh well, Fantastic Post!

My friend put in the code and it's really hard to see the difference. I don't understand how it sets a side of some RAM for the textures..if you have a lot of RAM, wouldn't it do it anyways? Doom 3 only takes about 200MB or so even though the minimum requirements are 384.

I think this configuration trick here are only for systems that have less than 512MB. Things load faster from RAM than from the HD anyways.

hmmm... the number in my file is 20... ah, well. 128, now!

[ghost2003]

I have 1GB of ram so should I change it to 682?

[Markoman01027]

Somebody please post their FPS before they apply the code and then the FPS after you applied the code with how much RAM you have on your system. That way we can see if it really makes a difference on different systems.

I dont know how to get my FPS...
