This is my first post, but I want to make it a good one. I don't exactly have the money for upgrades, nor do I really need them right now, but I'm running on what you would call a low-end system at it's specs right now. Rofl. But, I've got myself knowledge on the D3 engine, moddifing textures abit, and making custom made config files to run on a low end system. Now, Quake 4 only supports the Radeons 9700 and up, but I've got it working perfectly on this system.Quake 4 also requires a 2.0 ghz CPU.Again, no problem with that. Quake 4 needs 512 mb.That, I agree with.Won't lie on that. But now, the rest of the topic. ATI Catalyst settings. AA-Let App decide AF-Let App decide Texture Preference-Quality MipMap Detail Level-Quality Wait for Verticle Refresh-Off, Unless APP specifies QUAKE 4 settings Graphic settings-High Quality Specular-On Bump Mapping-on 640x480(Thought it was 800x600, but it's not.) Right now, the only problems I'm facing, are minor. 1.The D3 engine is unstable, and sometimes when it starts up, textures are rendered wrong and look terrible.(Which I still don't understand how, since it should be rendered automaticly to what I set)D3 engine problem.Not Q4.Does the same with D3. 2.Lighting.When you flash the light on your allies, their face just looks pale and no detail.When you are outside and you look in certain directions, the ground gets really bright.I'm working on a patch to fix that. I tried premade config files, and they didn't work for me. So, I altered the textures alittle, and made a config file.So you won't get as good performance as me. Here is my config file. To use this CFG file, open up a new notepad, copy and past this into your notepad, save it as autoexec.cfg and put it in the q4base folder.THIS CFG file is made for Radeon 9000, and 8500 models.You can use this for the Radeon 9200-9500, BUT you can get way better performance on them on a tweaked CFGs.NOTE-THIS ISN'T MADE FOR NVIDIA USERS.I haven't had a chance to pick up a nvidia MX series card yet, so this CFG is made to take advantage of the ATI rendering system, mostly the low default rendering system,Not the Nvidia system.Expect problems if you try to run it.(Tried it on a friends computer.Didn't work so well...) However, if anyone with the Nvidia card does have good luck with it without modding it at all, then horray for you. If you want to show the FPS, you'll have open the console and type in com_showFPS 1, as in the CFG file. My next project is to get the lower Radeon cards working on the ARB2 rendering system without the green models, and textures.
