Table of Contents • Introduction • History of PC-Games • Different types of Games • Hardware • Pros and Cons • Questions and Answers • Opponents Part
History of PC-Games • Grand Prix Circuit ( from 1988 ) • Aces of the Pacific (1992, 1990 Red Baron)
History of PC-Games Point and Click Adventures • Kings Quest I (1984) • Monkey Island (1990)
History of PC-Games • Comanche (1993 with “Vortex-Engine) • Civilisation (1993)
History of PC-Games • Lemmings (1990) • Wing Commander (1990)
History of PC-Games • Wolfenstein 3-D (1992) • Doom (1993)
Different types of Games • Simulations • Adventures • RPG • Strategic Games • Ego-Shooters • Jump ‘n Run • Flash • Combined Games
Simulations • Sports games • Flightsims • Other Vehicles • Economic Simulations • Real-Life Sims
Adventures Complete missions by finding items and using them in the right place …..
RPG Role Playing Game Kill the evil Gain experience and levels Find better equipment
Strategic Games • Build and Rush • Round based Games • Chess
Egoshooter • Single Player • Multiplayer
Jump ‘n Run • Super Mario….. • No games nowadays
Combined Games • CB’s have elements from different types of games • There are no further “fields” of computer games
Hardware • What do I need? • Prozessors • Graphics Accelerators • RAM • Problems by buying complete PCs • Upgrading your system
PC Mainboard CPU RAM HD Mouse Keyboard OS DVD/CD-ROM Internet Soundcard Speakers Graphics Accelerator Monitor Joystick What do I need?
CPU • What is the best CPU for my PC? • Different performances between AMD and Intel • Different “Names”
Graphic Accelerator • Technology • DirectX • Performance and Quality • Categories • Conclusions
Technologies • DirectX : Standarts for 3D and music effects • API – interfaces : Direct3D, 3DFX, OpenGL • Shader : Mathematical definition of a certain effect, e.g. a wet and reflecting stone • Textures : can be wrapped around any 3-dimensional object
DirectX 7 • Use of textures • T&L (Transform and Light) • Counterstrike and Unreal Battlefield 1942
DirectX 8 • Programmable Graphics Chips • Pixel and Vertex Shader • More realism • Pixelshader1.0- 1.3 with DX8.0 • Shader 1.4 in DX8.1
DirectX 9 • More complex shaders • Shader 2.0 and 3.0
Compare of Shaders • Same or similar effects • The lower the shader version the less intensive in calculations • Compatibility downwards
OpenGL • Comes from professional workstations • Most Direct3D effects can be made with OpenGL • For not predefined effects OpenGL extensions can be used • Not only for Windows
Performance and Quality • Performance is measured in FPS • For most applications 25 FPS is enough • For First Person Shooters at least 35 ( more is better)
Effects on performance • Resolution : 640*400 , 800*600, .. 1600*1200 • The higher the resolution the lower the performance
Effects on performance FSAA: "Full Scene Anti Aliasing“
Effects on performance AF: “Anisotrope Filtering”
Image Quality Because of “improving” the drivers to get a higher FPS-rate in Games, the image quality suffered. Benchmarks ( Programs to analyze your system performance) like 3dMark were the main influence on customers buying decisions. Cheating in Benchmarks was common during the last years.
Categories • Low-Budged : 0-150$ • Mainstream : -200$ • Enthusiast : 300$- • DirectX 7 8 9 • Shadercompatibility
Categories AGP or PCI-Express?
PCIx or AGP? • Most Cards do have enough RAM (128 – 256 MB), so that a datatransfer via AGP Bus is not necessary • Cards do have a bandwith of up to 30 GByte/s • PCI just 4GBytes/s
Conclusion • Nowadays it does not matter if someone uses/buys AGP or PCIx • Never buy a enthusiast category accelerator • The CPU and the graphics accelerator should be “equal”, otherwise the slower component would reduce the faster components performance too
RAM • Differences in FSB-Speed: 133,166,…533 • Rule : the more RAM the better, but today 1GByte of RAM is enough for all Games • Compatibility problems with “no-name” RAM
Problems by buying a complete PC • No exact description for all components • Often “no-name” components in use, which can cause troubles after upgrading a system • A lot of great sounding components, which are not so great
Upgrading a System If you want to upgrade in order of getting better performance in your games: • Check out your system, where to invest into a new component/s • If you have chosen a new component, check out if your system needs other upgrades ( ATX-Power-Supply) • Define your demands
Upgrading a System 4. Check out your budget 5. Compare products and prices by using the WWW 6. Never buy the newest, because of stability and price 7. Hope that everything works after installing ( 8. Overclocking)
PRO If you already have a PC, why not use it for games Best looking games, because of most developed technologies CONS Price Stability Compatibility of games to certain hardware components Some PC knowledge demanded ( compared to X-Box) New games need high-end equipment to be played Pros and Cons
