While mobile GPUs have become very efficient in the last two years, every little bit counts.įinally, for those who don’t mind getting their hands dirty, it’s possible to change the power curve of modern NVIDIA GPUs using MSI Afterburner. If you’re on a notebook, you’ll definitely want to make sure “Optimal power”, or at least “Adaptive” is selected in the global settings. You can then use “Prefer maximum performance” for only those titles. For demanding games that don’t play well with Optimal Power or Adaptive, find (or create) the required profile in the “Program Settings” tab of the “Manage 3D settings” page. The NVIDIA Control Panel allows you to configure profiles for games on a case-by-case basis. Unfortunately, this will increase the “idle” heat and power draw of your GPU, even when you’re not doing anything. Now, it’s tempting to hit up the driver’s global settings and set the power management mode to the aforementioned value and never think about it again. As the name suggests, this setting will run your card at its maximum clocks all the time. Newer NVIDIA cards feature several more options, such as “NVIDIA driver-controlled” and “Prefer consistent performance”, but the only other choice you need to worry about is “Prefer maximum performance”. However, Optimal Power adds another feature - it’ll stop the GPU rendering a new frame if nothing has changed on screen and instead reuse what’s already in the framebuffer. Both options will modulate the core and memory clock speeds and voltage of your GPU, increasing them during times of load and decreasing them when demand is low. Optimal power superseded the previous default, called “Adaptive”. This setting was introduced into the company’s video drivers with the GTX 1080, specifically version 368.22 release in May 2016. Having a limier at all helps steady the framerate, but it means you don't get the nice flow at the start of the game as a trade off for having a higher minimum in the gunfight.By default, NVIDIA sets the power management mode of your GPU (be it in card or laptop form) to “Optimal power”. What tends to happen in MW:O is the limiter alleviates the CPU botttleneck, more or less. I do like a framerate limiter, and think it's important to have one before relying on v-sync. The only trick to Adaptive is how you have to set v-sync in the game to off while the driver is set adaptive. There's also the "Adaptive Half" setting, for those whom hate tearing on the screen, but can't get the full "fps=Hz" thing to work out. The other thing with v-sync at this point in time is how handy the Adaptive setting is: If you're fps is not near the Hz of your monitor, it gets out of the way. There was an Direct3D Overrider that came with the original RivaTuner It's not updated anymore, and doesn't come with MSI Afterburner/ EVGA PrecisionX, or the underlining RivaTuner Statistics Server the two share, but it's not hard to find (read: ) But for the likes of us, it's easier to just set "d3d9_TripleBuffering = 1" in the user.cfg. There's also this old rule of thumb about setting triple buffering with v-sync: Well, the setting in the driver is for OpenGL only, so you have to find another way. While a Pre-rednered Frames of 3 is a defacto standard, you often have to turn it down with an active v-sync. The "Prefer Max Performance" thing just masks bigger issues If, at the end of a whole mess of tweaking, you can't find a setting that both keep the clocks up and not cost you some fps, then you can go "Max Performance."
