Australian chiming in. I think it depends on what you mean by dysfunction - the Australian electorate seems fairly evenly split between the two major parties, while adding some minor parties thanks to IRV (in the House of Representatives) and proportional voting (in our Senate). This has created a sequence of minority governments - where neither party has a majority in either chamber - or slim majorities in the lower house (where our Executive / Prime Minister is chosen from). That does create some gridlock and there’s no clear mandate for a change of direction. I think that’s still a fair ways removed from some of the major-party obstruction (specifically the GOP, and specifically Mitch McConnell leading the US Senate) which defines current US politics from the outside. I think IRV is a good thing for promoting a wider array of voices in politics, but I don’t suspect it will do much to prevent inherent checks-and-balances from becoming partisan roadblocks to policy.
