As many of you may have already discovered, there were some issues with SWTOR causing abilities on cooldown to appear like they were available to the player but without actually being usable to the player. This bug was reported by many and BioWare has an official response for us today.
Georg Zoeller reports:
Hi everyone; I wanted to give you all an update on the ability delay situation.
Thanks to constructive feedback from the community, including some great videos, we were able to identify an issue that could cause abilities on global cooldown to appear available to the player, resulting in unresponsive/ignored player input. A fix for the issue is currently scheduled to go to the public test server with our next update.
Additionally, we have located an issue that would cause player input for certain instant abilities to fail in frantic combat situations, resulting in unpredictable and frustrating gameplay issues for the affected player. A fix for the issue is currently scheduled to go to the public test server with our next update.
Finally, our engineers have identified an issue introducing a significant delay between player input and ability execution in certain game situations, most notably (but not limited to) fast paced PvP. The magnitude of the delay varies with a number of factors, including processor hardware, but can, especially on dual core CPUs, result in a very perceivable reduction in game responsiveness. We are in the later stages of testing a fix for the problem and hope to be able to roll it out to the servers very soon.
We’re still investigating a number of additional issues, along with some usability and quality of life improvements for responsiveness regarding player input, but the above mentioned developments should provide a very measurable improvement in combat responsiveness.
Thanks again for your patience and support and we hope to see you on the public test server to help us validate these improvements before pushing them to the live servers.
