Custom Resolution Utility (CRU)

Though I believe 1440p at 240Hz might at least in theory still require DSC on DisplayPort depending on the specific timings the monitor uses...or am I wrong?

2560x1440 @ 240 Hz shouldn't need DSC with CVT-RB standard at 8 bpc, but 10 bpc would require it. DSC doesn't necessarily disable DSR. I think the max pixel clock for DSR is around 1350 MHz for 3000-series GPUs, so anything below that can still have DSR even with DSC enabled. DSR is all or nothing. NVIDIA completely disables DSR and EDID overrides if any resolution exceeds the max pixel clock, so CRU would have no effect in that case.
