How to Install NVIDIA Drivers on CentOS 5 64bit

Okay, this is going to be really easy once you have the Elrepo repository. See my other post about installing third party repositories. Go ahead and get that setup then come back here for this:

yum install kmod-nvidia-304xx.x86_64 nvidia-x11-drv-304xx.x86_64 –enablerepo=elrepo

Hopefully it’ll modify your /etc/X11/xorg.conf file properly and then you can run `nvidia-settings` which should pop open a GUI for you that will help you setup even more.

It’s been a while since I set this up so let me know if I missed anything!

Their Final Destiny

Surely God is good to Israel, to those who are pure in heart. But as for me, my feet had almost slipped; I had nearly lost my foothold. For I envied the arrogant when I saw the prosperity of the wicked.

Surely in vain have I kept my heart pure; in vain have I washed my hands in innocence.

When I tried to understand all this, it was oppressive to me till I entered the sanctuary of God; then I understood their final destiny…

Faith Shaking Scientific Discoveries (Or Not)

Take-away: You know all those big big scientific discoveries that seem to shake your faith just a little bit more each time, if you’re being honest? Actually, they usually end up on the cutting room floor. Just wait a bit, and watch some Christian sources like AIG, CMI, or ICR, and you’ll see these claims often be completely retracted or significantly eviscerated. But you won’t usually find the mainstream media covering this because after all we-were-wrongs aren’t all that exciting. Rest assured all science inevitably, eventually, ends up agreeing with the Bible. Here are just a few of the big discoveries that later turned out to be largely hype…

Race 07 NVIDIA Anti-Aliasing

Update 2014-07-19: I found the solution. My original fix wasn’t even doing anything it was just using the 4x AA I set in Race 07′s Video and Language Options application. The real fix for me was upgrading drivers and then things started to work. Before upgrading my drivers NVIDIA Control Panel changes to AA didn’t appear to do anything and NVIDIA Inspector wouldn’t save my changes either. It just wasn’t sticking. After upgrading NVIDIA drivers it all started working. I used NVIDIA Inspector to set: Antialiasing – Mode: override; Antialiasing – Setting: 8x CSAA; Antialiasing – Transparency Multisampling: Enabled; Antialiasing – Transparency Supersampling: 8x Sparse Grid Supersamping (Sparse Grid is important, some things will still look jaggy without it); Toggle FXAA on or off: On; Anisotropic filtering mode: User-defined; Anisotropic filtering setting: 16x. Now even Monza 06 looks great which still looked poor after my previous fix. Good luck!

I finally found a little bit better anti-aliasing for Race 07 from this post on Race Department explaining that you can achieve slightly better anti-aliasing by using Race 07′s Video and Language Options application and setting 4x AA there and then also using the NVIDIA Control Panel to set: Antialiasing Mode: Enhance. I also set Antialiasing – Transparency: 8x; Ansitropic Filtering: 16x; Antialiasing – FXAA: On. It seems to look better. Still, some tracks like Monza 06 have a lot of jaggies. I suspect it’s just AA-unoptimized old track code. If you have a better solution I’d be glad to hear it!

htpasswd limits passwords to 8 characters (or: read the manual dummy)

Turns out htpasswd limits passwords to 8 characters in length by default prior to Apache HTTPd v2.2.18. I run CentOS 5 with HTTPd v2.2. I don’t rely on .htaccess password access for anything serious but I do use it as an https ‘front door’ for one of my addresses which does have its own properly secured password access. I’ve been running it like this for years and I was sure something funny was going on entering the username/password combo in there. I swore I was noticing incorrect passwords getting through. Today I decided to test it out thoroughly.

Sim Racing – 2014 Thrustmaster FSR World Championship

I’m really fascinated by this FSR World Championship sim racing series I just found. It’s a complete world series, complete with professional drivers and sponsorship, including call-by-call qualifying and racing. It caught be by surprise that we already have a fully virtualized, top-tier, professional sporting event that is a copy of a real word sporting event.

Logitech G27 900 Degrees Steering Across Racing Games

Update 2014-07-26 – 3: Handy online tool for calculating steering locks from wheel rotation and steering ratios. Also, some good reading on wheel rotation/steering ratio/steering locks.

Update 2014-07-26 – 2: I prefer realism in sim racing when I can get it, but I’m also not yet at the point where I want to research every car’s wheel rotation and steering ratio just to set that up in game to get a realistic feel. So I’ve settled on a GT-style 540degree wheel rotation and 18degree steering lock for 15:1 steering ratio. iRacing appears to be the only game I have so far that automatically applies a 900degree setup to real-world wheel rotation and steering ratio in each car they have. For all other games you have to set it manually and often that means every time you get into a car you have to load your custom setup file. After googling a lot, I find most people are happy with a middle-ground GT-style 540degree wheel rotation with 15:1 steering ratio which needs an 18degree steering lock setup. This is a generalization, not all GT cars use those numbers, but what you get in the end is one wheel setup for all racing sims where you get a consistent car turn feel across different car types.

Update 2014-07-26: Understanding SimBin Steering Sensitivity: The following applies to RaceRoom Racing Experience, Race 07, GTR 2, and I assume all SimBin racing games. I finally understand what they’ve done with steering sensitivity. 50 is linear, but either side of 50 is not linear-but-different-ratio as a I expected. I finally got it when I was really looking at the steering meter. If I turn the wheel 90deg three times it goes from nothing to full. At 50 each 90deg takes up the same amount of space – so each 90deg physical wheel turn actually represents 90deg virtual wheel turning (broken animations aside). But, at 100 the first 90deg takes up the most, the second 90deg takes up less, and the third 90deg takes up even less – so each 90deg physical wheel turn may not actually represent 90deg car turning. At 0 it’s the other way around. So I choose 50 for steering sensitivity in SimBin titles to ensure that all degree ranges on my wheel rotation act and feel the same way.

Update 2014-07-19: I finally got 900 degrees in Race 07. It is, in fact, the same method as RaceRoom Racing Experience (Set it in the Logitech Profiler and then set the Steering Lock in the Car Setup) but apparently the steering wheel animation won’t be correct if you do that. That would have been okay except there’s no default steering lock like RaceRoom Racing Experience has so you have to set it on every car. I guess that’s technically correct but more hassle than I wanted so I went back to Logitech Profiler default degrees for Race 07. I wish these games would just do the ‘auto-magic’ thing like iRacing does.

Update 2014-07-08: I finally got 900degrees in RaceRoom Racing Experience: (1) Set it in the Profiler, (2) set it in R3E under Vehicle Settings > Wheel Animation (remember this is only animation it has no effect on how it feels), (3) go in to Control > Advanced Settings and set Steering Lock between 28 and 32. You need to google about steering lock and the ratio between that and the rotational degrees of your steering device. I just found the 28-32 metric after reading some discussions. For 540 degrees I’ve seen recommendations of 18-22. I believe the same steering lock applies for Race 07 but I haven’t tried it yet.

I loved the way iRacing was so easy to setup for the 900 degree turning ability of the Logitech G27 so I tried RaceRoom Racing Experience and Race 07 and was very disappointed there was no way to get that linear steering working when the G27 was setup for 900 degrees. Well, it’s not a real fix, but it’s here’s a decent work-around…
