A word about "FPS"
What are we looking for in gaming performance wise? First off, obviously Guru3D tends to think that all games should be played at the best image quality (IQ) possible. There's a dilemma though, IQ often interferes with the performance of a graphics card. We measure this in FPS, the number of frames a graphics card can render per second, the higher it is the more fluently your game will display itself.
A game's frames per second (FPS) is a measured average of a series of tests. That test often is a time demo, a recorded part of the game which is a 1:1 representation of the actual game and its gameplay experience. After forcing the same image quality settings; this time-demo is then used for all graphics cards so that the actual measuring is as objective as can be.
Frames per second
very limited gameplay
average yet very playable
best possible gameplay
- So if a graphics card barely manages less than 30 FPS, then the game is not very playable, we want to avoid that at all cost.
- With 30 FPS up-to roughly 40 FPS you'll be very able to play the game with perhaps a tiny stutter at certain graphically intensive parts. Overall a very enjoyable experience. Match the best possible resolution to this result and you'll have the best possible rendering quality versus resolution, hey you want both of them to be as high as possible.
- When a graphics card is doing 60 FPS on average or higher then you can rest assured that the game will likely play extremely smoothly at every point in the game, turn on every possible in-game IQ setting.
- Over 100 FPS? You have either a MONSTER graphics card or a very old game.
Today an article slash guide dedicated on overclocking the GeForce GTX Titan. Can we take it to 1100 MHz ? Sure we can. Armed with a new trick or two overclocking will never be the same though.
GeForce GTX 680 Overclock Guide
Today an article dedicated on overclocking the GeForce GTX 680. Can we take it to 1300 MHz ? Yes we can.
Radeon HD 7870 Overclock Guide
This is a Radeon HD 7870 Overclock Guide. We'll overclock based on a mild voltage tweak. By doing so we drive the R7870 into R7900 series performance. All you need is some free software and a little time to precisely determine and pinpoint your maximum yet stable overclock.
Radeon HD 7950 Overclock Guide
We take a Radeon HD 7950 overclock it the normal way and then voltage tweaked. So that way we will demonstrate not one, but two maximum overclock conditions alongside TDP, heat, noise and performance levels.
