Fix for screen lag when running GPU
I'm putting this in the news/announcements because this may help people in many projects, not just PrimeGrid.The downside to having an efficient GPU app is it's likely to produce a lot of screen lag. In some circumstances there's an easy fix that won't impact crunching speed.If the lag is *only* happening in web browser windows, but not elsewhere, the problem is that the web browser is trying to use the GPU to speed up its screen rendering. That gets clobbered by the crunching happening on the GPU.The browser should have a setting to enable or disable using the GPU, and it's enabled by default. Disabling GPU "acceleration" in the browser should completely eliminate the browser lag.In Chrome, the setting is "Settings" -> "Show advanced settings" -> "Use hardware acceleration when available".In Firefox, the setting is "Tools" -> "Options" -> "Advanced" -> "Use hardware acceleration when available".It's likely a similar option exists in IE.
