^ This. Also, unfortunately, I had major issues with Sony's stack too.

Check the RTINGS latency database for the full technical breakdown.

Like someone mentioned, that Sony Bluetooth stack is just a mess. I’m actually gonna disagree a bit with the idea that you need to stick to expensive console controllers though. If you want to kill the lag on a budget, you should look at controllers that use a 2.4GHz USB dongle rather than just straight Bluetooth. I’ve been super satisfied with this approach because it bypasses the TV's internal wireless issues entirely. Here are some budget gems that worked well for me:

• GameSir T4 Pro Wireless Controller - solid feel and usually under $40.
• Logitech F710 Wireless Gamepad - older but the 2.4GHz link is rock solid.
• EasySMX ESM-9101 Wireless Game Controller - super cheap but works great. Honestly, save your cash and grab something with a dedicated receiver. It’s been a total game changer for my living room setup and I havent had a single complaint since switching.

Honestly, the Bluetooth lag on Sony TVs is a total mood killer for cloud gaming. I went through the same thing with my setup last year. Even though its all Sony, the Android TV Bluetooth stack just isnt optimized for low-latency gaming like a console is. If you want to stay under $70, I really recommend the Microsoft Xbox Wireless Controller Carbon Black. It connects easily to the X90L and honestly feels way more stable than the DualSense on this specific OS. Another solid pick is the 8BitDo Pro 2 Bluetooth Gamepad. It has a toggle on the back for Android mode which helps a ton with compatibility issues. The real secret though... if you still feel lag, dont use Bluetooth at all. Get a controller that supports a 2.4GHz USB dongle. The 8BitDo Ultimate Wireless Controller 2.4G comes with a dock and a receiver you can plug right into the TVs USB port. It bypasses the TVs internal Bluetooth mess entirely. TL;DR:

• Best native feel: Microsoft Xbox Wireless Controller Carbon Black
• Best for lag reduction: 8BitDo Ultimate Wireless Controller 2.4G using the USB dongle
• Best value: 8BitDo Pro 2 Bluetooth Gamepad Lemme know if you need help with the button mapping once you get one set up, its kinda finicky sometimes.

@Reply #3 - good point! I definitely agree that a dedicated USB receiver is way safer than trusting the built-in Bluetooth. You gotta be careful tho, because those Sony ports are prone to interference if they're crowded. Quick question, are you sitting more than ten feet from the TV? Also, is your wifi router right next to the screen? Signal overlap can totally tank your reliability regardless of the hardware you use.
