This thread has come about due to the old one being fucked up by trolls. So a notice to all trolls, you WILL BE KILLED ON-SITE! Right, to business. This new thread in this very post will contain all current information, observations, facts, and user experiences about this modded driver I have to hand. What YOU need to know There is nothing special about this driver, no magic pixies are suddenly going to sprinkle their magical dust on your on-board Realtek chip and have it sounding like a Asus Xonar D2X. The purpose in this driver is to simply squeeze every last bit of performance there may be out of the Realtek HDA Codecs. All I have done is what KainXS asked me to do based on his research, nothing more. Is what your doing illegal? Not in the slightest, and heres why; 1. I'm not asking any money for this. 2. I'm not changing any DLL files or the like. 3. What I'm doing to enable this stuff is just text file editing . 4. I'm not "stealing" anything. (How can you steal whats volintarily and readily available as free downloads?) 5. Its not Creative drivers I'm messing with, just Realteks own drivers. 6. The crapative software suit is available as free download from gigabyte. Where do you get the knowledge to mod these drivers? I'm a hacker of sorts and can patch most things. My skills come from modding games mostly (compiling, decompiling, editing, etc) For more specific tasks I talk to people I know who are real software gearheads, namely, their the super clever people who are responsible for such things as the software for retina security devices. As such they can do this kind of stuff with their eyes closed Facts 1. This modded driver is a larger install vs. a vanilla Realtek driver install for what are currently unknown reasons. In my case a generic Realtek driver install shows as around the 5MB mark in Add/Remove programs for my Realtek ALC1200 Codec, whereas the modded driver install is 60MB. 2. The X-Fi MB software works in Win XP, not Vista. I've heard of a modded X-Fi MB software package that works in Vista, but from what I know this supposed modded software package still does not work for people using Vista. 3. I do NOT have a key for the X-Fi MB software, your on your own there. 4. People using Realtek Codecs complain of partly broken EAX 2.0 implementation in Realteks drivers, my modded drivers do not appear to suffer from semi-broken EAX 2.0 implementation. (Tested with Bioshock) 5. RMAA tests have been done comparing a modded driver to stock Realtek drivers and clearly show improvements. 6. The driver works in Windows 7 7. CPU usage with the modded driver is 5-11%, up from 4-6% with the stock Realtek driver. 8. Placing a Aluminium or Copper heatsink on your on-board audio IC will help reduce EMI and electronic crosstalk, resulting in a little audio improvement. 9. KainXS and myself came up with these Realtek X-Fi modded drivers first. The original release was 03-08-2009, 06:15 PM Linky. So if anyone trys saying we didn't, you know thats not true. User experiences & observations Listed in no particular order are snippets taken from the old thread from various users running XP or Vista 32/64bit regarding JUST the modded driver. 21 people can't all be suffering from the plecebo effect Chewing the fat 1. Apparently, the Microsoft driver for HDA audio installs a Creative filter by default. However, one possible explanation to account for peoples claims of much better audio quality with these modded drivers is that due to the namechange incorporating "X-Fi" into the name, the Microsoft driver package for HDA audio, could, in fact, have 2 filters built into one. One of the filter paths would be for "generic" audio (Realtek, ADI, Via codecs) while the other path is for "Creative" audio. Same principle as for video cards, developers often create specific ATi / nVidia codepaths based on what hardware is detected. 2. Its possible that due to the namechange in the driver that the Realtek installer detects the hardware slightly differently, resulting in Creative-esk audio, which would also explain why EAX 2.0 seems to work fine with the modded driver, and not with stock Realtek drivers. I think that covers everything. I will edit / updat this post as needed.
