If you go to the EVGA main website, click the Support tab, under Product Info. there is an option for Drivers and BIOS. Select 'Other Products' tab and use the drop downs to find the mouse. UNCHECK the box that says 'SHOW LATEST DRIVER' and you will see a full list of past drivers.

Hi,
 
I am sorry for any confusion and I can confirm that we are looking into if FW34 is available to assist.

I could downgrade with a trick to FW35 and same issue.
 
If you could provide the EVGA_X5_34.hex file it would be enough.
 
Thank you for your help.

hello,im a new happy owner of this mouse,except for the feets(a little too thin for me),i love the torq x5 ;) after few days playing cs and few test with enotus mouse tester and paint.tested with software installed but off and tested only 400-450-500-550 dpi,1000hz,windows sens default,accelleration off. im sure some (too much) smoothing is there,it also appear not very constant but come as spikes..enotus tester read each time a different value varying from 12% to 20% and more.i got many gaming mouse and none have  such random smoothing results(roccat pure military,logitech g100s,intellimouse,cm alcor and few more)in the worst case the results only differ by 3% and none go above 14%.also on paint making straight lines,circles and writing something, is clearly visible that some lines are good,uniform and not jagged at all,other are a little jagged,other more jagged and other much more.however this isnt stopping me from having very good games even after so short time i own it,but this weird act of the sensor is always a little perceptible especially on desktop.so pls evga can you investigate and see if you can fix it?thx evga.

I concur this mouse is phenomenal. The software it comes with has many nice and beneficial features, kind of similar to that of the Razer/TRON software (which I had). So it's really nice to have. I like how I can customize the buttons on the right of the mouse to be used for other purposes other than raising/lowering the DPI polling rate.
