It will definitely be a deal breaker for me, I am very disappointed with PD because they were among the first to bring us a racing sim but now it seems like the rest of the sim games are surpassing GT6.
After trying afew PC sim's I am convinced that PD will not surpass the up coming titles on PC for 2014. The PC sim's have way surpassed PD. I think PD will be in for a big surprise when Project CARS hits the PS3, that will probably hit them hard and to be honest they kind of deserve it for being so stubborn. I mean are they deaf?
If they are testing and driving all sort's of cars with racing exhaust's then go back to the office and listen to their own sound, if it was me I wouldn't want to go back to the office it would probably make me physically sick to hear those vacuum cleaners from the storage cupboard after hearing driving top of the range sport's cars.
Come on PD wake up, all you need to do is run Forza 4 and GT5 together with same cars, surely Kaz can tell the difference in what sounds more realistic, stop hiding behind a lie to cover up the embarrassing sound effect's.
*EDIT*
I think I would even stay with rFactor 1 over GT5 to be honest. I've been on PC now for the past 6 months and installed rfactor with a hand full of mods (who says I cant have Porsche?) and probably a hundred tracks. When I drove I thought ok the graphics isn't that good but can live with it because sound and physics on the wheel is very good.
Now I wish I got into rfactor instead of buying GT5. This time i'm sticking to PC sim's, why? Because there is at least 5 top sim developing companies so they all going to make sure they can deliver the best experience. After Project CARS i'm sure PD will do something about sound. GT6 will still be a great game don't get me wrong I just think PC sim's is better in every way.
The only way I will buy GT6 is if PD upgrade to real engine sound not some crappy Dyson sound. I want to hear what you hear in a real race car.
Well it's clear to me that PD will not succeed in GT6 but we will soon see for ourselves, I don't have hope for PD for a number of reason's not just sound. I'll give a comparison with GT's closest rival at the moment.
FM4 and GT5 has been compared endless times and is still an on going discussion, I went and tried FM4 on wheel roughly when Porsche was released as DLC. Reason why I went over to FM4? Choice of cars, Sound and Porsche. Comparing the two games from my experience as a wheel user without being bias is easy because i'm just looking for a whole package for a motor sport game and not just graphics and physics.
As a wheel player on GT5 since release I was naturally going to compare wheel force feed back and GT5 wins that hands down for me. But that's where it stops because FM4 does everything else better, for example the PP system in FM4 is a much better thought out system, everything has performance points, tyres, gear box, exhaust, brakes, clutch, literally anything upgradeable has PP's and also FM4 does not have an engine limiter (who's idea was it to put this crap in a sim?). The engine limiter is a really bad idea, no other sim has it and is a stupid idea why was it put in?
Then there is the choice of cars, Turn 10 tried to give a good variety from a lot of racing catagories. FM4 has a lot more to offer, better choice in cars. No 10 same model car or standard models, just a well made put together content. GT5 on the other hand the only thing going for GT5 is Force feedback from the wheel and the graphics of premium cars and tracks. Everything else in GT5 suck, not enough wheel options for wheel users the PP system, the engine limiter, awful music and sound effects. Forza on the other hand got everything right except the most important thing, the wheel.
