Greetings Elhanan,
Thank you for the considered response, I actually appreciate it. I would not claim to be the only person experiencing stability issues with DAI and for a fact I know that I am not. I have also gone to some extraordinary lengths to test the problem. You see I build custom PC's for select customers as such I have an array of hardware at my disposal that I can use for testing purposes... This is what I did...
My methodology was straightforward, I kept same/similar components but swapped them and then re-tested. After each swap a fresh OS installation was performed. This is what I did....
1. Drop all Overclock configurations including XMP.
Even though the 5960 supports 3,000Mhz RAM doing so requires a 125mhz strap with a sufficient multiplier applied to it, this constitutes an overclock and overclocks can incur some instability in in a system by exposing flaws in manufacturing processes. I suspect as well that not all applications benefit from overclocks so I dropped the seemingly stable config I was using and reverted to defaults, to no avail.
2. Memory swap.
The RAM sample I used initially was a 32GB 3,000Mhz Corsair DDR4 solution, I also had a brand new spare G.Skill 3,000Mhz DDR4 kit which I decided to use for testing purposes. The swap went satisfactorily, of course it is important to note that although the samples are designed to function at 3,000Mhz they only do so when XMP(AUTO) is enabled or a manual selected set of values are provided to the BIOS of course even if its only the RAM being targeted its still an implied overclock. Without XMP most DDR4 3000 modules default to 2133Mhz. The RAM swap resulted in no difference to DAI's stability.
3. GPU swap.
I used two GeForce Titans in this machine originally, and I hypothesised that despite only DAI crashing that perhaps an unknown fault was causing the application to trip. I swapped the two Titans for another pair and earned the same result DAI crashing to desktop. I have swapped both cards once more for a pair of Titan X's and have encountered the same result.
4. CPU swap.
The 8 Core Intel i7 5960X is one of the most powerful commercial market CPU's available but its also fairly new. I had decided to swap my CPU with a newer production run version with a higher stepping in case a flaw in manufacturing has not been documented sufficiently. This resulted in no discernible difference to the games stability.
5. Motherboard swap.
I use an Asus Rampage V Extreme motherboard in my computer. This mobo certainly lives up to its 'Extreme' monicker, however a complex device like this can suffer complex problems that may result from improperly applied firmware and microcode. I have witnessed some systems that have reported unsupported configurations because flashing their BIOS resulted in the erasure of the Management Engine Firmware causing MEI to fail to communicate with the board. Despite the RVE having two system BIOS chips I decided to replace my motherboard with a spare just to see if this made a difference, much like CPU's different board revisions are produced over time and I sought a revision of the RVE that was later than my own. This resulted in no change to DAI and its stability.
6. PSU Swap
I ordinarily use a 1,475Watt Thermaltake Power Supply in my computer. This supply is an 80% Efficient Platinum rated PSU with excellent resilience. I decided to swap this supply for a Corsair supply of a similar power rating. Just in case an electrical fault is encountered when specific power conditions are reached. This resulted in no change either.
7. Audio
Generally speaking I UTTERLY despise onboard audio solutions, irrespective of whether or not they are 'good enough' to this end I use a Creative Sound Blaster ZxR for my audio and I swear by the quality of the audio that card produces. but in order to eliminate it as a possibility I swapped it for a spare Asus Xonar Essence STX that I had, which is also an absolutely superb audio solution. The card swap made no difference to the game.
8. Finally throughout all these tests I also ran Battlefield 4 without any issue at all. Which is significant since it uses the same engine, perhaps an earlier iteration.
I'm sure you would concur that my testing has been thorough. There isn't a single component in this machine that hasn't been swapped but irrespective of what has been swapped the outcome has been the same. I am leaning more to the notion that this title has an issue with higher end hardware. If this is the case however, then it poses a significant problem to PC gamers specifically since we do upgrade our machines regularly. All I can say is that the issue is not the computer and I'm not the only one experiencing it, but when I can happily get around GTAV, blow up ships in Homeworld Remastered (which incidentally uses OpenGL), Render heavy video workloads for work enjoy Elite dangerous and the other 90 odd games installed but have issues with DAI, well I have to wonder....
