50% of the time measured frames is doing roughly 60 FPS for Radeon HD 7990, the GTX 690 hovers at 53 FPS here.Ībove, the cards at 2560x1440.On this 30 second run the graphics card manages to remain roughly below 30ms as you can see again both cards show stutters, we again can confirm these as visible on screen. Here we plot FPS and place it in relation to percentiles. Above, a percentile chart of the 30 seconds 2560x1440. We now step into multi-GPU rendering with the GeForce GTX 690 and the feisty Radeon HD 7990. Huge spikes above 40-50ms can be considered a problem or indicate a low framerate. This happens with ALL cards tested at any resolutions, so it is game-engine or system related. This is another and valid way of looking at performance.Ībove, the cards at 2560x1440.On this 30 second run the graphics card manages to remain roughly below 30ms as you can see both cards show stutters, we can confirm these as visible on screen. To the right you'll notice that the last 5% of the frames is at 20 to 30 FPS or lower. 50% of the time measured frames is doing roughly 50 FPS for GeForce Titan, the R7970 GHz hovers at 38 FPS here. It's just an additional page or two of information that from now on we'll be serving you.Ībove, a percentile chart of the 30 seconds 2560x1440. 
Bear in mind that Average FPS matters more than frametime measurements. Below I'd like to run through a couple of titles with you. What do these measurements show?īut basically what these measurements show are anomalies like small glitches and stutters that you can sometimes (and please do read that well, sometimes) see on screen. Higher latency can indicate a slow framerate, and weird latency spikes indicate a stutter, jitter, twitches basically anomalies that are visible on your monitor. We have a detailed article ( read here) on the new FCAT methodology used, and it also explains whay we do not use FRAPS anymore.įrametime - Basically the time it takes to render one frame can be monitored and tagged with a number, this is latency.
