Ultra Street Fighter 4 has experienced a bumpy start on PS4.
The brawler made its PS4 debut earlier this week, but has been plagued by issues since launch.
According to Eurogamer, players have complained about input lag, sound bugs, visual glitches and menu slowdown.
Series regular Guile has even been dishing out invisible Sonic Booms.
The problems are so bad that Capcom has pulled the PS4 version of Ultra Street Fighter 4 from the Capcom Pro Tour.
Capcom has acknowledged the issues in a statement to fans.

"SCEA and Capcom are currently looking into the issues that some users may be experiencing and are working to resolve them as quickly as possible," the statement reads.
"A lot of our more competitive players have wondered how the USFIV version of PS4 will affect them and the tour.
"To that we'd like to advise that the integrity of the Capcom Pro Tour is a top priority for us and we will continue to work with tournament organisers worldwide to ensure that the highest quality event will be run.
"Each region will maintain its current hardware standard for the remainder of the 2015 Capcom Pro Tour until otherwise announced.
"We will keep you updated as to when the PS4 version of USFIV will be integrated into the Pro Tour."
Ultra Street Fighter IV introduces five new characters - Rolento, Elena, Hugo, Poison and Decapre - and six fresh stages, as well as Omega Mode which gives characters new moves and properties.
The PS4 port was handled by Capcom and Sony's Third Party Production studio, and is available as a digital download now.
