major frame drops in game with xbox pc games

Hi TiMacmillan! My name is Ricardo an independent advisor ready to help you with this situation!

It sounds like the issue it's with the Mouse and Keyboard, it could be due to software incompatibility if you have RGB devices you should try disabling all that software

Also if you start playing with the controller and then switch to play with the mouse it could happen as it updates the input method

Actually frame rate drops are frequent in many games. This morning I was playing L4D2 and the frame rate drops when the horde of infected come running in my tv screen. In Halo Wars the frame rate drops when there are too many units on screen at the same
time. Frame rate drops are a common occurrence on many games, it is not a fault with the games but instead a limitation on the xbox 360 hardware.

zit's been a great and unique experience. However, I've lately been thinking of gaming on a pc since the frame drop on my Xbox happens quite frequently.

Enabling fixed V-Sync is not always ideal. For an example if you play a game synced to 60Hz and the frame rate drops below 60fps, the game is automatically re-synced to 30fps. If it drops again (below 30fps), it is re-synced to 15fps and if the same happens
again, frames are dropped (meaning it won't be send to the screen). So to provide somewhat stable rate of motion , developers disable V-Sync, which means the majority of frames rendered by the console are send to the screen. But that leads to two different
types of problems. 1. Unstable motion and 2, tearing. This is because it's not possible to fit number other than 30 and 15 into 60. So some developers program the game to drop frames while maintaining somewhat stable motion (or repeat the frame 2-3 times).
End result: Clean frames but the motion isn't consistent, which is ok for certain games but not for all games. The other option is to merge two frames into one, this leads to tearing (as you're clearly witnessing atm). This provide consistent motion at the
cost of visual quality. Certain developers isolate tearing near the top (HALO 3, ODST and Reach all programmed to tear at the top) but not developers have managed to achieve this. If you're playing it on the PC, you can modify the files or force the GPU to
enable V-Sync, but on console, there's no such option.

can you please clarify what the issue is.

if you are on PC and playing on a high graphical setting that your PC cannot handle it can make the games frames drop a lot
