Half Life 2 GPU Roundup Part 1 - DirectX 9 Shootout

Turning on Anisotropic Filtering
For the most part Half Life 2 doesn’t absolutely beg for anisotropic filtering to be enabled, but there are definitely a few situations where image quality could be improved by turning it on.
Looking at the peach colored metal platform towards the right of the images before you can see some of the benefits of anisotropic filtering in Half Life 2:
Aniso Disabled
8X Aniso Enabled - ATI
8X Aniso Enabled - NVIDIA
So there's definitely an improvement with 8X anisotropic filtering enabled but the difference in image quality between ATI and NVIDIA is tough to quantify. The two look quite similar in our opinion, with ATI getting the nod for slightly better image quality (the difference is quite subtle).
One issue we found in Half Life 2 with anisotropic filtering enabled is that the amount of resulting texture shimmering was borderline unbearable. The shimmering was worse on NVIDIA cards than on ATI cards, but it was definitely present on both. Part of the cause of the shimmering was the fact that all modern ATI and NVIDIA cards have resorted to a less ideal method of distance calculation for anisotropic filtering, which contributes to the shimmering issues we noticed under Half Life 2. With the release of the GeForce 6 series, NVIDIA moved to a method of anisotropic filtering using a weighted manhattan distance calculation, similar to what ATI had been doing for quite a while. The problem with the weighted manhattan distance calculation is that it is much more sensitive to the orientation of a surface in respect to the viewer, which can cause more of these shimmering issues.
NVIDIA’s NV3x line used a Euclidean distance calculation that was less sensitive to surface orientation and thus reduced some of the shimmering issues we encountered under Half Life 2.
There are some levels in Half Life 2 where enabling anisotropic filtering improves image quality, but then there are others where image quality is improved at the expense of increased texture shimmering. Rest assured that the shimmer occurs on both ATI and NVIDIA cards and it seems that the only way to get around it (unless both ATI and NVIDIA choose to employ different methods of anisotropic filtering) is to leave it disabled if it bothers you enough.
In terms of anisotropic filtering image quality, we just showed that we were hard pressed to find any image quality differences between ATI and NVIDIA’s solutions under Half Life 2. In motion however, NVIDIA’s drivers did seem to cause more texture shimmering than ATI’s with anisotropic filtering enabled.

I've also noticed that having the steam client running in the background can place quite a load on your entire system! After downloading all the content to cut down on network/disk/buffering wierdness I did some tests benchmarking UT2004 with the ons_dria demo from nvnews and noticed that my fps drops up to 10 when steam is running in the background!Might it be possible to compare performance between the retail version of Half-life 2 and the steamed version available for internet purchase to see if there's any sort of performance difference? Or does the retail version just run through an offline steam client anyway? (I bought over web)

if your game crashes when switching to fullscreen it is because you have refresh overrides in place.add:
-width X -refresh Y
to your command line, for example
-width 1024 -refresh 100
it fixxed all my video problems.

#10 - That's a pretty stupid thing to say. Kyle used the cards that his readers were most likely to buy; I know I wouldn't waste my money on a non-BFG nVidia 68xx card, and I know most other gamers wouldn't either. It's a part of [H]'s focus on doing real-world-style benches instead of OMG LETZ C IF NV RULZ ATI 2DAY IN HL2!!111111With all that said, it's great to see stiff competition in the video card arena, finally--should make for exciting product lines on the next go-round.

HL2 World is reporting that they've found a working Half-Life 2 multiplayer built in to standard retail HL2. Here's the story, including how to do it:
Here's how:
net_start
sv_lan 0
deathmatch 1
maxplayers (whatever you want)
map (mapname)
restart
It will add you to the master server and it works. I know, it looks like the leak, but I assure you this is the retail HL2.
They have a screenshot, as well as a test map for you to check out if interested. Head on over to HL2 World for the full story.

Get back to Half-Life 2? Why? There's no point other than the fact it's a pretty single player game. If I wanted single player than I would have raved about Max Payne 2, which I didn't. Why Valve didn't think to make a Half-Life 2 MP side is beyond me. That's where the market is these days. Single player games, you play them once and you are done. Multiplayer is always changing. I don't want to wait for any stupid MP mod either. Curse you, Valve, for making us wait a year longer and then only giving us one piece of the cake!TrungRacingDev - Thursday, November 18, 2004 - link
you do realize that the fx5900 is default directx 8.1 right? if u think its beautiful now...try a directx 9.0 card =)Motley - Thursday, November 18, 2004 - link
I'm glad I didn't read this article before actually playing HL2.My system:
P4 3.4GHz, 2GB Ram
5900 Ultra video card
ASUS P4P800 Motherboard
I was playing HL2 at 1280x1024 with 6xAA, and 16xAnitropic Filtering, with everything else turned on to maximum. Besides a half-second stutter just after loading a new level, the game played GREAT, looked GREAT.
Then again, maybe I'm not expecting the world, but, I can say that I was pleased, and maybe the x800 or 6800 can turn out better numbers, HOWEVER, at no time did I feel that I needed (or even wanted in the slightest) faster frame rates, or smoother gameplay. It just owned from the beginning to the end.

Anand, In light of the significant ATI X800XT DX9 (HL2) performance over the nVIDIA 6800 Ultra, would you today favor the X800XT PE graphic card in combination with the MSI K8N Neo2 motherboard? In your last High-End Buyers Guide (30 August) you recommended the nVIDIA 6800 Ultra be used with the MSI K8N Neo2 because Wesley thought that motherboard performed "a bit better" with a nVIDIA card. What would your recommendation be today? Can we anticipate another High-End Buyers Guide this month(its been 3 months)? Billblckgrffn - Thursday, November 18, 2004 - link
I know, I know, but if gf2 can play at 800*600 MQ than maybe they can handle 1024*768...that would mean that a bunch of my friends wouldn't have to upgrade from their $60 cards, and they would be overjoyed :)
