It frequently drops down to 40-50 fps but this benchmark shows it running at an average of 74.6fps.

Full rig specs:
R9 290 TwinFrozr gaming edition
FX6300 w/ Antec Kuhler 930 at Stock
GA-78LMT-S2
8GB 1333mhZ RAM
XFX XXX Edition 750w

Is it being bottlenecked by the cpu? If so can I overclock it with that budget mobo to 4.2ghz if I don't touch the voltage?

Yes your getting core throttle! Look at the memory 4th graph down its a solid 1250mhz, look at the core 3rd graph down its all over the place. 280x or 7970 doesnt suffer this and has a solid fixed core, hence for many better benchmarks and gaming performance from the cheaper card.

Its caused by AMD powertune which to keep noise and temps down, instead of increasing the fan speed more, it throttles the cpu core clocks...

Edited it in! Doubt it's the problem since I know its a quality PSU.
What gives man I read people maxing otu games on 1440p while I can barely manage 60fps on 1080p.
Also MSI AfterBurner shows 100% gpu usage while playing :/

i would say its due to the 40 dollar mobo you are running, its a 760g with a 3 phase vrm, it is likely overheating very quickly and throttling like crazy. this all points to that since you said it frequently drops

are you on the f5 revision to support this cpu as well?

Well, the superior CPU, RAM and PSU that they used could give them a +5-15 fps advantage but +25fps is a bit too much. Have you configured the r9 to Uber Mode?

Also the motherboard chipset may cause some issues with the pefmomance

Should run better than that.
Apart from the possible mobo:
Make sure you're using the latest drivers, there were issues with earlier revisions not reading the GPU fan speed correctly causing the card to reach its thermal limit and throttle.
Make sure your system doesn't have a dozen or so other programs running while you're gaming-you may laugh but it's been done so I have to make the point.
Use a CPU temperature monitoring program, it could be the CPU is overheating and causing the problem.

These drivers business is confusing as hell. Ive read people saying don't upgrade to the latest betas since it causes problems while others including you say upgrade to the latest one. =/ I have 13.11 beta though. Is that fine?

Will try your two suggestions.

In the options menu, have you disabled the physics option? This seems to be specific to nvidia physx and I got a large frame rate boost when I disabled it. If i recall its not under graphics options but somewhere else, been months since I played TR.

Can't find a physics option anywhere. 🙁

And I forget I'm not actually running it on "ultra" right now since I've got tesselation turned off....and still cant get constant 60fps fuck.

To be fair the toms test used very high end hardware like the 3970x. I think its entirely possible that the cheap mobo and FX6300 could be causing the slower performance.

Whats your CPU usage in the game?

Okay I guess upgrading to the lastest 13.12 non-beta is worth a shot,


Id be pissed if it's because of that. Not going to drop another 1000 usd in upgrades just to get 60 fps on 1080p.

Will check CPU usage now.

I would say overclock the FX6300, but I think you might struggle with that mobo...

HWinfo says all cores maxed out at 100% but average was 33-55% across all cores,

CPU 0 Temp 30c avg
Mobo 42c
CPU 40c

Turned up my fans rpms and opened my 550d's top and front panels. FPS is slightly better. Less drops and only goes down to 50-55fps.

The reality is, Tomb Raider heavily pounds the CPU in some spots at Ultra settings. You don't have the fastest CPU, so drops into the 40's is expected in some areas. You can drop a few settings to ease up some, but it won't help a lot on those minimums.

I'm fairly certain that the only thing that will help is a faster CPU.

Sounds like the core throttle issue to me, install afterburner and setup the On Screen Display (OSD) to show core clocks in game. Run you game and see if they stick at 1077mhz if running in OC mode, or 977mhz if running in gaming mode. If they fluctuate all over the place, report back and i'll tell you how to fix :)

Its caused by AMD powertune which to keep noise and temps down, instead of increasing the fan speed more, it throttles the cpu core clocks instead, this is great for reference AMD cards with noisy hot coolers which reach 94*c , but aftermarket cards which aren't even hitting high temps (mine tops out at 68*c!) the 35% core throttle is hitting performance heavily.

You can fix it by enabling unofficial overclocking mode in afterburner, and then setting the core to 978mhz or 1077mhz (depending if you have an OC card) and the power % to +50. Try that and repost your screenshot after gaming of the core.

(also disable overdrive in CCC if you have it ticked, and don't use the gaming apps which allow you to choose silent, gaming or OC mode for the card, as both of these will overwrite/conflict with afterburner settings)
