Hey guys today I’ve got a very special video that I want to share with you. Basically I’ve been recently playing
GTA V for PC and I’m really enjoying it, like crazy amounts. It’s a
really great game great optimisation and everything. So I wanted see what I could do to improve the game
experience like improve the FPS or how far I could ramp up the graphics
settings. So obviously to do that you have to find
out what’s bottlenecking. So I started the journey and I was trying to figure out what was
bottlenecking by going on online forms first and GTA is an open world game and that means the CPU does quite a lot of work, so it’s quite a CPU intensive game. Obviously it’s brilliant graphics-wise but
it’s quite CPU intensive like rendering
pedestrians and draw distances and stuff like that is heavily dependent on the processor. Now, basically I haven’t upgraded my
processor since I first got a proper gaming computer and the processor I’ve got is an AMD Phenom II x6 1090T. Now it’s quite an old processor it’s about 4 years old I think it came out in 2011 which makes it four
years old I’ve overclocked it to 3.8GHz and that’s the highest clock that I can get stable. I thought I could get it to 4GHz but apparently GTA is a better stress tester than prime95
or IntelBurnTest so that told me that I needed to bring
it down to 3.8GHz to make it stable which is exactly what
I did. So now it’s stable at 3.8GHz, with no crashes
at all with the game. If you guys have an overclock and have had crashes and you haven’t got crashes in prime or IntelBurnTest, then trust me it’s probably your overclock which is causing the game to crash or hard
reset in my case which happened a few times. So, back on track: old processor my graphics card is an R9 280X so it’s pretty good above the recommended specs by quite a long way the 7850 is recommended I think, so there we go. On your screen now you can see my settings – the settings
I will be using. No MSAA obviously as that is a framerate killer that just kills it on any card. I actually
just fiddled around with it for fun and tried it on 8x MSAA. It looks way better or 8x than 2x. There’s basically no framerate drop. The massive framerate drop is from
0x to 2x and then it gets less exponentially. Anyhow regardless of that I am going to be showing you my stock speeds so the stock graphics card speeds of 1070 and 1600. This is the
benchmark that I ran and these results I got. So as you
can see all we’re really interested in is the top box of ‘Frames per second (higher is
better)’ and mainly looking at the right
hand side column so 51, 60, 52, 67, 53 those are the sorts of frame rates that I got during the
benchmark. Now I will be showing you a side by side
comparison of the text files that the game outputs when you
run a benchmark so don’t worry about that. I decided that instead of… to find out how bad the
bottleneck of my processor was on the graphics card I thought, right
I could do it one of two ways: I could either overclock the
processor to see how many extra frames I get, or underclock the
GPU to see how many less frames I get. So obviously it’s easier
to downclock the GPU so that’s exactly what I did and I started by using MSI Afterburner as every avid overclocker does and nothing was happening literally nothing was happening. You can
see the results now on the screen – there’s basically no difference I tried it on 100MHz core less 200MHz core less, 300MHz core less and nothing was happening. I was like come on MSI Afterburner must be
broken or something! So, I decided to use Catalyst Control Centre. You can do much lower core clocks and memory clocks using CCC than MSI Afterburner because MSI Afterburner is not meant for underclocking, it’s meant for overclocking so why would they bother? So, I did it again… on CCC and as you
can see on your screen on the left is the stock at 1070 and 1600 and on the right is the the underclocked scores. So, as you can see by dropping the core
clock by 120MHz and the memory clock by
100MHz nothing changed. Absolutely nothing. In
fact the results are slightly better. Right, onto the next one this is with a 850 clock and 1400 memory which means that it’s now been dropped
by 220MHz on the core and 200MHz on the memory and as you can see again there were no differences. If
anything, they’re slightly better. So that means that currently my CPU is still the bottleneck. So I decided let’s go down a bit further.
I started making the steps I that went down in a bit bigger so here’s 700MHz so that’s a 370MHz drop in core and a 400MHz drop in memory and you can see it for yourself –
the results are exactly the same they haven’t changed yet again. That’s 370MHz less on the core clock. That’s ridiculous! Now this is where things start to change. At 600MHz core you can see
that the framerates are much more consistent which means that
the GPU is the bottleneck in the system. So you can see in the first result there wasn’t much difference but in the second result you can see that 7FPS difference. Third result was basically
the same. Fourth result you get a 6FPS difference and the last result you get a 2FPS difference. Now I did run this after I ran the lower clocks because I was
trying to find out where exactly the CPU was being the bottleneck, so this is the equilibrium position or slightly
under it where the GPU is now the bottleneck. Now I thought to myself let’s just do it for fun let’s go a bit lower. So I went down to 550MHz on the core clock and 750MHz
on the memory clock and as you can see, the first result doesn’t change. Second result 12FPS. Third result 2FPS. Sorry this is ridiculous it starts
at zero! Pass three is 12 difference again and pass four is 5 frames difference. So now you can see the CPU is outperforming the GPU. Why not do it for fun let’s get up the idle clocks like the lowest it can go when
there’s no games running or it’s just YouTube, the GPU downclocks itself to 300 core and 150 memory. I thought let’s run it – why not? As you can see the results are quite
drastic. There is a 30 FPS difference in the majority of them. There is 30 in pass zero, 40 in pass one, 35 in pass two, 50 in pass three and 35 in pass four. So there you can see it. My CPU is bottlenecking my GPU by quite a long way. So I can underclock my GPU. I can nearly halve the clocks on my GPU and still get the same performance I’m getting. 600 core and 900 memory is the point at which the CPU starts going “hey I’m better than you hahahaha”. But apart from that my god I did not realise how bad
it was. So, that is an excuse for a processor
upgrade! I’m probably going to wait until Zen. I want AMD to be good, but they’re not at the moment. So I mean I
don’t know how much and FX 8350 will be an improvement because I can’t guarantee an overclock so I don’t know how much of an improvement an FX 8350 will be on my 1090T, so if I can hold out for another year and a bit then maybe I’ll pick up a Zen processor and if Zen sucks, then sorry AMD the Blue Team is the winner. So those are the results and yeah feel free to leave your comments in the description. I’ll be uploading
a Gyazo link to my graphics settings and yeah that’s pretty much it. Thank you guys for watching hope you
enjoyed it. Hopefully it was very informative. Thanks for watching!

    That 1090T can be pushed until it is stronger than the newer FX series. The only other option would be to go Intel. AMD Phenom were beautiful chips. I had one I pushed up to 4.3 with an AiO.

    i noticed that my CPU was bottlenecking when i upgraded from a GTX460 to a GTX770 and had ZERO fps improvement in Star Trek Online (which i was playing a lot at the time).
    Swapped that Q6600 for a Core i5 2500k and bamm FRAMES.

    Since then i always have an eye on the Aida64 stats on my Logitech G15 display showing me CPU and GPU load…
    of course some games are more cpu dependent than others…
    DirectX12 will get rid of a lot of CPU overhead responsible for a lot of bottlenecking… i hope that the DX12 adoption rate on the Dev side will be a bit higher and faster than previous DX versions.

    anyway my Core i5 2500k @ 4,6GHz seems to still be a pretty good match to the GTX980 with a 144Hz screen. I'm quite happy with my performance at the moment.

    i think the last AMD i had was an XP 1700+ … AMD was still good back then… but now they are just going for the budget segment, not for high end.

    this site will tell you if your system is bottlenecked http://www.game-debate.com/games/index.php?g_id=1308&game=Grand%20Theft%20Auto%20V&popSysReqWidth=0&popSysReqHeight=0&popSysReqRAM=8&popSysReqGPU=GeForce%20GTX%20780%20Ti%20Gigabyte%20GHz%20Edition&popSysReqCPU=Core%20i5-3570K%203.4GHz#systemRequirements
    if your CPU bottlenecks your system you should try overclocking to minimize your bottleneck

    I run GTA V on my 12-core Xeon workstation. The CPUs are X5670s at 2.93ghz. I have the same GPU as you. I found that hyperthreading kills performance on my machine, and that disabling 4 cores out of the 12 helps. That being said there's always two cores running at 80% while the others chill at a mere 40% or so. I'm guessing the best bang for buck CPU setup for GTA V would be something along the lines of a 3930k overclocked to the absolute brim.

    The easiest way to see if your CPU or GPU is a bottleneck, is to run MSI AB or EVGA Precision-X with an on-screen display showing your CPU and GPU usage while playing a game.

    when i play overwatch, or really any other game, i get around 54-60% gpu usage. When I play gta, which is more demanding in the first place, i only get around 40% usage and it is stuck there. Any suggestions?

    I have an i5 7500 with a GTX 1070 and GTA 5 is the only game where i frequently see the cpu at 100% usage. I'm not even using max settings and the framerate dips into the low 50s/high 40s in some areas of the game, but usually hovers around 60 fps. I'm just worried about a bottleneck.

    my i5 6400 bottlenecks my rx 580 to the point where 1050ti gets more fps with i7 . its so annoying when i drop to 50 fps in public sessions
