I've contacted Dell's support and they know NOTHING.Īny sugesstions here? I'm getting REALLY crazy. (It's not a temp issue, I've also clean reinstalled drivers, I've set all the power management options on the laptop to "performance", I've disabled any background program, well, almost everythinh) I've tried lot of things and nothing was successful. GPU Z PERFCAP DRIVERSI've done some googling, and from everything I've read, this PerfCap reason occurs because the Nvidia drivers think that the GPU is not being utilized, and therefore is reducing the voltage to the GPU in an attempt to save battery life on the laptop (despite the fact that I'm plugged into AC power at the time). Also, the GPU clocks get downclocked, the voltage gets reduced and the GPU load gets reduced to something like 20/30%. If I run the Techpowerup GPU-Z utility, I can clearly and unambiguously see that this is caused when there is a PerfCap of reason: Util occurring. Games which do not use the GPU as heavily are not as problematic when the issue occurs, though, the issue does still occur, because I can see it happening with GPU-Z. Though the degree to which the game is affected by the problem varies. Also, I have noticed that the problem occurs in different games, as long as they use the Nvidia GPU. To the contrary, the problem occurs completely independently of what I'm doing in the game or how complex the graphics are in the game at the time. This isn't because I've reached a moment in the game where there are extra graphics or draw distance or effects on the screen. While the problem is occurring the game is essentially unplayable due to the massive amount of control input lag making mouse selections nearly impossible. When the problem occurs, the frame rate is terrible for about 60-120 seconds or so (the length of the problem is also random), then miraculously the frame rate goes back to normal. This happens randomly, but on average it occurs approximately once every 5-20 minutes of gameplay. Sometimes when playing a 3D game with the Nvidia GPU, there are periods when the game's frame rate drops suddenly to a slideshow. GPU Z PERFCAP HOW TOOn the other, you'll be able to see its internal status in real time, especially useful if you have some type of overclock on the card, so you can measure GPU temperature, frequency, fan speed, and voltage you can also save all of this monitoring report in an external text file so you can analyze the data at a later time.Can anyone offer a suggestion as to what might be causing the following situation to happen? I've been trying all sorts of things for days, trying to narrow this down, and I can't figure out how to fix this. On one hand, you'll have all of the hardware's technical information: GPU model, integration technology, quantity and frequency of the internal memory, type of bus it’s connected to and bandwidth. Not only will you be able to view your card's model and its internal memory, but you'll also have access to other, more specific information. GPU Z PERFCAP WINDOWSGPU-Z is a precise and accurate monitoring tool for Windows that allows you to see the internal features of your video card. In spite of having different authors, GPU-Z shares the interface and main features of CPU-Z, only it focuses exclusively on your video card's specs. CPU-Z is one of the most famous and trustworthy programs for monitoring the internal features of your PC.
