A large number of people, especially those running AMDs, find that their CPU is being underutilized in some areas, causing severe framerate issues. This is true even for those with hardware exceeding recommended specs and with graphics at lowest settings.

Tera has problems telling the CPU's dynamic frequency scaling to step up, so it stays at a lower frequency. To remedy this, go to BIOs and turn off Speedstep for Intel processors and Cool n Quiet for AMDs. I don't know what the cause is, but it could be Tera's problem, AMD's problem, or something in Windows 7 that's preventing frequency scaling from working correctly.

The problem for me started in CBT4 and didn't to this extent in any prior betas. Sometimes my FPS would drop to 8-12 during some fights and remains low in towns. Now it stays at 40+ during fights and caps at 60 in towns. Note that this shouldn't be a permanent fix to the problem, as throttling is a powersaving feature and is also crucial for laptops. EnMasse/Bluehole needs to patch this up if possible so we don't need to disable features on the CPU.

or you can just go in control panel, in the power options and Set tp High Performance, then your cpu wont throttle for power saving.

Thanks.

I always see Cool and Quiet, can anyone tell me what it does by disabling this?

Will my system start running hot and loud? >_> serious question. Lol. I've never [filtered] with it due to the fact that it sounds like something necessary.

Hey Invalid.

Cool and Quiet basically downclocks and undervolts your CPU. When you're not doing anything intensive, such as browsing the net or posting on these forums, the CPU goes into this low power-state, cutting down the clock speed and lowering volts going into your CPU. Thus saving you energy, wattage, money on the power bill, etc. It'll ramp right back up to the set clock speeds and volts once you do something intensive with your system though, such as playing a game or something like that.

Less volts going to your CPU and lowering the clock speed means it runs "cool" as well and may have an affect on your CPU fan if it's controlled by your mobo, running cooler means the fans RPM's will lower thus making your system more "quiet". It's a great feature.

Anyways, if you disable Cool and Quiet your PC will always run at your set voltage and clock speed level.

Let's say you're running a AMD Phenom II X4 965(my old chip)

Stock frequencies: 3.4ghz
Stock volts: 1.32v

With Cool n' Quiet enabled and you're not doing anything intensive:
Frequencies: 1.2Ghz
Volts: .80v

With Cool n' Quiet disabled your CPU will always run at the first examples speeds and volts. Causing a little more heat and MAYBE, just maybe, a little more noise due to your CPU fan having to work more.

Er, if you knew some of this [filtered] already, sorry! lol

I did know a little bit, but that was a perfect explanation and much appreciated!

Sounds like the best bet, would to monitor your CPU heat if you disable this, and perhaps buy a better cooling system if you notice craaazy things.

lol, you're welcome!

But yeah. Monitoring works.

And as long as you have a decent heatsink you'll be fine with Cool n' Quiet disabled, no problem. Your system might idle a little higher but that's pretty much it. The load temps, of course, will still be the same with or without CnQ.

Does modifying the power options to High Performance not work?

I will try turn off speedstep next beta.

Nah. It doesn't override the BIOS setting. You need to manually change that within your mobo's settings.

I have my system's Power Options set to "High Performance", Processor states set to 100%, my i5 2500k still goes into the low power state(which I want).

I have another fix which I think should work. Disable hyper-threading if your processor doesn't support it or if you have a core 2 series, then set try fiddling around with core priority. I will try this next beta, for some people it made their framerate go from 10 to 40.

I have a similar problem but with my GPU instead. My video card never goes above 20% use and I get about 25fps AT MOST. Here is a screenshot of the most FPS I could possibly get along with my hardware http://puu.sh/m3Go

my CPU stays at 60% so I doubt that's a problem, 3ghz core 2 quad should be enough for Tera. My settings are greatly above Tera standards especially since everything is properly overclocked. I get 65-70fps average playing Tribes a game that uses the same engine with better graphics, I run it maxed with 4x AA. Here's proof : http://puu.sh/mNub note the GPU use, the CPU use is the same as Tera.


I made a thread about this here http://tera-forums.enmasse.com/forums/cbt4-bugs-suggestions/topics/Game-Optimization-and-Nvidia-drivers

I really hope EME fixes this, especially since they don't develop the game it is hard for them to get enough support to have nvidia/bluehole make changes for the game, and the game has been out a whole year I'm really scared that I'd have to play tera at 20fps which is nearly unplayable and I get headaches from it. I guess I can only hope for the devs to do their best and make fixes to the engine.
