gtx 780 running low clocks on driving games

has anyone got any idea on why my gtx780 decides to run racing games with such low clocks, it has done this on every single racing game i own, grid 2, project racing but is fine when i play any other game. I use a logitech g25 for the racing do you think it could be this which could be conflicting somehow? im running the racing games at 1440 nearly maxed out on the settings so one should think im taxing the card enough to stay at boost clocks but it seems no matter what settings i use it down clocks itself after a while playing the games. any help would be grand cheers.
 
It might just be that if your running V-Sync the driving games are far less demanding? Grid and similar codemasters games always seem to run really well. Take some screenshots of GPU-Z sensors page during game play so we can see the clocks. I've never had any issues with G27 drivers running 780/780SLI/780Ti so I do doubt that's related.

That is interesting. It could be the game's engine and is not tied to a specific game's genre. But I get what you're saying - racing games have less static images and shouldn't it be refreshed constantly for each frame 'cause everything move all the time? Logically, GPUs should be working harder with racing games than other genre.

Could it be an optimize (I'm saying good logic, effective utilization and efficient coding here, not porting as the word is now commonly used for) engine? 'Cause it can lessen stresses on hardware (GPU, CPU or IO) right? Or even by using tricks, I don't know, like not rendering static image over and over or color compression to reduce redundancy like in movie codecs, etc.

I notices that GTA V is not using my 780's full clock speed all the time, it fluctuates, and the game has a driving system too. This differs with MetroLL, DAI and FC4, these games are using full clock all the time (well, FC4 slows the clock down on map and static menus). All my games are set with V-Sync on.
 
Thanks for the input guys, will take some screen shots later after work to see what the clocks are doing

With regards to the racing games that are giving me issues, when I first boot them up all is well with good frame rates but then the frames slowly seem to drop until the point in which the games become a stuttering mess then unplayable that's when I tab out and notice the clocks have dropped right down, last night prime example while playing the game the clocks started off at 1126 or thereabouts but when I tab out they were sitting just above 500mhz which is crazy low for running a 3d application, thing is it's stopping me using the wheel as intended so I just don't bother playing these types of games
