From a spectral point of view, the distribution of the frequencies is nearly ideal.
A bass boost of 6 dB (bass and treble effect) gives 6 dB roll off for the whole range.

However, that's not the problem. I think that the audio plays too fast.
Set the rate in the track drop-down menu to 44100 Hz (48000 Hz is checked).
Doesn't that sound much better, in particular the female voice?

This is a sample recorded directly with Audacity.

Edit: This time I recorded 16bit and 96,000 Hz both settings in Windows and Audacity, then the sample reduced to mp3 default 128bit

@Robert
I emailed the sound file to you.

So I've seen, thank you Koz.
It is difficult to nail down the difference. I presume that the Audacity recording is the target sound.
In direct comparison (so far as it is possible), the mp3 seems to have more sound effects (sword clanging and ringing) than the duller wave file.

This might be due to different channel balancing/-mapping. I don't use Fraps so I can't tell.
Using the bass and treble effect should help somewhat (+10 dB treble and perhaps a bit of bass too).
The speed is apparently the same.
By the way, 96 kHz is way too high for such a recording imo.

I can't technically tell it but for sure Fraps added a strange effect to the sounds

Tried it (struggled to find the filter as I was using older Audacity 2.0) but I think that that doesn't effect the specific issue.

And here I think that you anticipated my following feedback.
I recorded at 96 KHz just to see if there was any change so indeed for gaming recording and Youtube 44K KHz is plenty of quality.
By the way, when I tried to upload the sample on the forums I faced with the size limit so to reduce its size even more I reduced the bit rate to 64bit then I listened to it and discovered that the issue I'm talking about was empathized even more.
I artificially created and empathized the audio effect (which I'm complaining about) even more so that is why I recorded at 96 KHz, I don't know how to technically explain it.

To make a selection fit on the forum, the usual technique is to reduce the length of the show, certainly not the quality which is usually the whole point of the posting. An alternative not mentioned in the posting instructions is to post a very high quality MP3 (128 Mono or 256 Stereo instead of a WAV. You can get many more seconds of show time posted and most times, the quality difference doesn't matter.

If we're trying to diagnose a technical or bit-by-bit wave error, then yes, you need to post the actual WAV.

Yesterday I had a problem with Audacity 2.0 (working on 2.0.5 now) always saving same files size (which was too big) it didn't matter how much I was cutting it then I gave up because it was a bit late.
However, here are for clarity both samples from Fraps and Audacity recording saved at 256 bit.
I think that there is some difference.

It's a rather subtle difference isn't it?
(the spectrum differs only marginally)
You should actually record the exact same battle scene with both, Audacity and Fraps.
Of course, this may not be possible due to driver restrictions/exclusions.
Can you tell which input devices serve as source in Fraps and Audacity respectively?
Fraps uses normally a automatic detection but you can set it to a manual input assignment in order to be sure.
Changing the fps rate might also have some impact.

In the mean time I'll try a different game play recording software.

I struggled so much with this piece of audio, my purpose was to upload game play to Youtube but also I've had chances to practice with Audacity.
I played the audio on other computers and it sounded differently, I would say just normal.
Then I checked the computer I'm working on, the Windows Media Player equalizer's bands from 2K to 16K were set to the extreme top!

I would recommend people sharing their computers to create a personal user name profile and always log in with a password, also one person should act as an administrator and set the proper limitations to all users so that they may not change system's settings.
When dealing with video and audio editing it's of vital importance to know your computer and mostly important not to let anyone change any setting.

Audacity is an amazing software and it's high recommended in professional private institutes and universities, last but not the least this forum is a vital core for the support of the software.
Thanks everyone for giving professional support here and for your patience!
