Slipstream was featured in the humble monthly march 2019 package and that brought in a lot of new players to the game. And with the new players, new bugs are found. Some users reported huge FPS drops when using a bluetooth Xbox One controller, specifically when the game tries to make the controller vibrate, such as when you start to accelerate the car. This issue seems to be happening exclusively on windows, with a wireless xbox one controller. Unfortunately I don't have a working xbox one controller with me at the moment, and we're in the middle of a holiday week here in Brazil. The earliest time I'll be able to send a definitive fix to this problem will be wednesday (march 6th), but thursday is a more realistic estimate. For now, the only temporary solution I can suggest is to disable vibration on the settings menu. This seemed to fix the issue for everyone who reported it. I hope to provide a definitive fix as soon as possible. Another issue that gets reported to me from time to time is that the graphical settings don't work, or something similar. Here's a step by step guide to the graphics options, i.e. it applies to all the options above the "apply graphics settings":

• change the settings you want, such as resolution, fullscreen on/off and filters
• go to 'apply graphics settings', press confirm
• choose 'keep the current settings' on the next menu and press confirm again
