IMO if you're just going to run a VT and scale everything back up both compositing and 4k cause way more problems than they're worth. Give me tearing, pixels, and unupdated danged regions any day over input latency.
- vetinari 6y agoAt 4K, we are still in the almost 32 MB framebuffer range. At 60 Hz, that's nothing a PC class hardware would have problem with. Mobile GPUs of few years ago, yes, that could be beyond their capabilities, but not iCore Intel GPUs and ddr3 or ddr4 ram. If you are that sensitive to input latency, run your terminal full screen. In full screen mode most compositors skip the compositing step, as there would be nothing to compose with. So in this case, your single, full screen window does direct scan out.
